ROOM AND BAUD?

Editor:

1 recently saw the following ad on BUY-
PHONE. Los Angeles' "Computerized Yel-
low Pages":

"ROOMMATE WANTED: I am looking
for a roommate to share a two bedroom
apartment in San Gabriel. CA. Rent is
$225/ month. You also may have partial use
of my IBM PC computer."

Is Los Angeles setting a trend towards
"Room and Baud?"

A CHARITABLE CONTRIBUTION

Editor:

San Pable Institute, a non-profit public-
charity, is forming a computer education
program for economically disadvantaged
children in San Francisco, especially those
whose families would otherwise be unable to
afford computers and extensive instruction.
The club is a free service program of San
Pablo Institute. No membership fees arc
charged nor are children expected to pay for
any club services. The computer club offers
programming instruction and gives children
an opportunity to meet and share ideas with
other children interested in computers,
allowing them to constructively apply their
time, talents and intellect.

The San Pable Computer Club is seeking
donations of computers and peripherals.
Equipment that is donated will be lent out to
club members for "hands-on" learning at
home. All donations are tax deductible and
we pay for shipping.

Get a tax break on that old clunker and
receive the satisfaction of knowing that the
computer you cut your teeth on is being put
to good use by a kid that couldn't otherwise
have a computer at home. To donate, please
write me: San Pable Institute. 234 Mullen
Street. 94110.

INFORMATION PLEASE

Editor:

First. I would like to congratulate the
entire staff of the Rainbow for producing a
truly fine magazine. 1 have been unable to
find another magazine that is even compar-
able to yours. Thanks!

Also. I have been looking for what is
called a "host" program for my Modem 1 1. Is
there such a program around for the CoCo?
If anyone could help me I would greatly
appreciate it. Mv address is 14 Sunset Trail.

CAR GAMES WHERE ARE YOU?

Editor:

I am a subscriber to your helpful maga-
zine. I am also a very concerned game
player. My favorite kind of game is a car
game. In the past months I've been looking
for a program for a car game and there
doesn't seem to be many in your magazine. If
anyone who also reads the magazine is inter-
ested in helping me. send in your car games!
Please!

DRAWING DILEMMA

Editor:

Does anyone know of a machine language
program to draw a line between two points
in the highest graphic mode (6R|? I have a
Ml. points routine and a great three-dimen-
sional object rotation program that puts
people to sleep watching Color basic draw.
Please help: 2232 Grand Ave.. I430I.

Joseph Fiore
Niagara Falls, N. Y.

Editor:

I need a program that I can use my CoCo
to send Telex overseas. I am not very famil-
iar with this subject and so I sincerely wish
you can give me some advice.

What kind of program I am looking for?
Does anybody already have the program on
the market? (for CoCo)?

Sure appreciate a quick answer. I am
forming a company now and really wish my
CoCo can do something for me. Thanks a
million.

Roland C. Wong
El Monte. CA

Editor's Note:

There is a system from Western
Union called "Easy Link" that can be
used to send Telex, cables and all sorts
of other stuff. You can buy a subscrip-
tion from ComputerWarc.

Editor:

For a long time now I have wanted to start
my own BBS. but since I am only 14 years
old. I haven't had a lot of money for a BBS
program. Then when I got your November
issue on Data Communications. I was thrilled
when I read the "Supreme Sysop" programs,
but I have a question: Do I have to have a
disk drive and disks to run it. or can I use
cassettes?

Ken Clark
Washington. DC

Editor's Note:

Sorry Ken, a disk is required for
this particular BBS.

COCO POWER

Editor:

Are CoCos better than Vic 20s. Commo-
dore 64s. TI-99/4As and Atari computers?

I'd like to know because my friends think
that CoCos are second rate computers and
that Vic-20s have better graphics than CoCos
do. Also I'd like to know about how many
software programs there are for the CoCos.

I think that your magazine is the best
TRS-80 Color Computer magazine. Thank
you.

Eric Onoferychuk

Editor's Note:

Give your friends a copy of the
Rainbow and let them look at the ads.
Ask them if all of these programs can
run on their computers.

Editor:

I would like to upgrade my computer to
64K. Being in Germany. I am unable to get
the job done by Tandy, however. I under-
stand there are chips on the market which
arc easily fitted by the owner. If you could
give me any information on reliability of
makes and ease of installation. I would be
very grateful.

Philip Judd
Detniold, Germany

Editor's Note:

You need eight 4164 chips. Most
suppliers give installation instruc-
tions.

Editor:

Has anyone ever discovered bow a pro-
gram tape(from CoCo)can be loaded intoa
Model III? I want to use the Model III print-
ing facilities but cannot load my CoCo type
into the Model III. Can anyone advise? My
address is Box 504. 12839."

I have recently purchased a G E M I N I- 1 OX
printer. I am very pleased with its capabili-
ties, yet I am having a difficult time under-
standing how to use the Bit-Imaging and the
downloadable characters. "The manual thai
came with it was much too vague for me to

appreciated.

ADVENTURE: PITS AND TIPS

Editor:

I tried out many Color Computer maga-
zines and found yours was the best. There
was so much in it compared to other mag-
azines.

I just purchased two Adventure games:
Pyramid and Madness and the Minotaur
from Radio Shack, about two weeks ago.
Right now I am stuck in both.

In Pyramid, I can't make it past Pharoah's
chamber, the one with the serpent in it. And
in Madness and the Minotaur. I'm having
problems getting out, killing monsters and
obtaining spells. If you know the solution to
any or all of my problems, then send it to me
at: 203 South Road, 06447.

Jay A usl
Marlborough. CT

Editor:

To all those Adventure addicts out there
who are having difficulty getting past the
snake in Pyramid or are stuck at the sarco-
phagus in Sands Of Egypt, don't despair.
Here are some hints from someone who was
once in the same predicament. In Pyramid.
the bird statue will defeat the snake when
thrown if you find a way to carry it. but
beware the ANKH STAFF. The last trea-
sure that no one can seem to find is within
the maze, past the pit. When you find the pit
in the ma/.e, go east once more then northw-
est, and don't ever waste the coins on
batteries.

In the Sands Of Egypt you must place the
scepter on the sarcophagus to get to the trea-
sure room. If you didn't get this far, then you
must go into the pool and drain it, then go
down with the torch lit and use the boat and
shovel as an oar. What ever you do, don't

drink the water in the stream. Good luck and
keep Adventuring.

Steve Jeromos
Hauppauge, NY

HINTS AND TIPS

Editor:

Frank Garhau's line voltage fluction prob-
lem is not uncommon. May I suggest that he,
and all others with this problem, purchase a
constant voltage transformer. Not only do
these correct for line voltage fluctions but
also offer excellent protection against over
voltage surges. For computer use only, a
30VA size is adequate however to feed the
CoCo and the disk drive, a 60VA size would
be required. The best known supplier of CV
(constant voltage) transformers is Sola Elec-
tric Co., 1717 Busse Road, Elk Grove Vil-
lage, 111. They can supply the names of a
distributors. Allied Radio, Ft. Worth, Texas
also has CV transformers.

CHANGING A ROUTINE

Editor:

In POKEing up the Disksort routine
submitted by Malt Stephens on Page 64 of
the December issue, I found that it per-
formed two sort routines, the primary sort
was on the "EXT" and secondary sort on
"FILENAME," hence the final product is

alphabetical on the EXT first and FILE-
NAME second. In order to list the "FILE-
NAME. EXT" in alphabetical order, the fol-
lowing changes were made. Delete lines 190
thru 260 and make the following change to
line 270.

270 FOR X=l TO S:ES(X)=MID$(FS(I).
9.3):NEXTX

By making this change, the routine runs
very good in sorting the directory by file
name.

Since all of my files and other material is
listed in alphabetical order I found this rou-
tine extremely helpful in allowing my direc-
tories to also be the same way. Thank you.
Matt, for an excellent utility.

Editor:

You know how good Rainbow is so I
don't need to tell you that, just that 1 love il
and don't even thumb through the other
CoCo magazines any more. Here's a handy
hint I don't think I have heard of anywhere:

For short but frequently used programs, I
keep one working copy of each on Realistic
Endless Loop cassettes (R.S. Cat. No. 43-
401 for 20 second loop or 43-403 for 15
second loop). The big advantage is never
having to rewind these utility tapes. Just
insert cassette, CLOAD. and RUN. This
saves lime and you don't feel guilty about
wasting tape by CSA VEing only one pro-
gram on a regular cassette.

I'm using a I6K ECB CoCo, Epson MX-
80 with Micro Works S/P interface and a

FIREFLY'S REVENGE

Editor:

1 caught an error in Josef A. Laakc's pro-
gram, The Laserworm and The Firefly. In
line 26 it reads:

26 POKE 65495.0: CLEAR 350.16375

The periods should be commas. The line
should read as follows:

For those going to disk systems for the
first time and experiencing difficulty with
the high speed POKE (65495.0) do the fol-
lowing:

Use a soldering iron or wire cutters to lift
one leg of C85. This is a little disc ceramic
capacitor near pin 40 of the cat ridge connec-
tor. I have an "E" revision CoCo. The CP
number (C85) may be different on other

A WINNING TIP

Editor:

I truly enjoy your magazine, and was
especially interested in Joe Kohn's Color
Blackjack which appeared in the October
1983 issue.

I understand why Mr. Kohn chose to ran-
domize his bets, but in reality few people use
this method.

A winning tactic would make use of the
card counting techniques spoken of in the
article. 1 offer the following lines of code to
do just that.

Anyone interested in how the calculations
were arrived at would also be interested in
the book "Beat the Dealer" by Edward O.
Thorp.

WHAT'S IN THE NAME?

Editor:

Ever since I bought my 32K Color Com-
puter with a disk drive in January, I have
met sharp prejudice when I mention that I
have a Color Computer. I love this machine
and find it to be more powerful than machines
costing two and three times more. So I set
out to find the reason for their ridicule; and I
can now share my findings with you. It's the

WILD AND CRAZY CRIME

Editor:

I am enclosing the original of a clipping
from the Des Moines Register dated Octo-
ber 13, 1983, captioned "Woman sues over
computer message." The body of the short
article indicates she filed the lawsuit (civil,
not criminal) because her boyfriend called
her computer terminal and left a message
intended to intimidate and annoy her.

IOWA CITY, IA.(AP)— An Iowa
City woman claims in a lawsuit that a
former boyfriend harassed her by send-
ing a message to her computer ter-
minal.

In the suit, filed in Johnson County
District Court, Lisa Schmidt alleges
that James Brucher, also of Iowa City,
sent a harassing message to her com-
puter terminal. The message, accord-
ing to court documents, said Schmidt
was a "wild and crazy woman."

Schmidt said she and Brucher had
dated, but were not dating al the time
the incident allegedly occurred.

Schmidt claimed Brucher typed the
message with the intent to intimidate
and annoy her.

My first reaction was amusement, but on
reflection, it occurred to me that many per-
sons might not realize that in Iowa and many
other states, it also constitutes a crime to use
the telephone in this manner. With the pro-
liferation of home computers and modems,
people should be made aware that they

A WEAVING WEB

Editor:

1 have an idea for what 1 think will bring
some Rainbow reader/ programmer a lot of
fame. My idea is for a game for the CoCo
called "The Tholian Web." Remember the
famous Star Trek show? If I could write the
game I would, but I'm not that good yet. The
object of the game would be to try and beam
aboard all persons alive from a damaged
starship. before the Tholians complete their
web, then escape the web. The other starship
would be "blinking" out often to make the
game hard. Also, include 100 people on the
ship and your transporter can only beam six
at a time. The ship will appear at different
locations, unknown to you. This game could
be done in Extended basic. And Rainbow
could print it! So, all you Rainbow readers
who are looking for a new project. 1 dare you
to try this one. Who knows, you may be
famous for it one day! Mv address is 1502
Holly St.. 39437.

Whether your interest is in quick-
reflex arcade games, sport
simulations, science fiction adventures
or war games, you're sure to find
many challenging contests from
Avalon Hill's Microcomputer Games.
Your only problem will be deciding
which one to pick!

Shooloul Screen

SHOOTOUT (at the OK Galaxy)

30 ALIEN WARSHIPS HAVE ENTERED YOUR PATROL ZONE. OK,
shields up?, energy level . . . cheek, azimuth set? Yup. This may sound
like the latest summer space movie thriller but in fact it's the preparations
YOU will make when playing Avalon Hill's new arcade strategy game
SHOOTOUT AT THE OK GALAXY. Over 2 years in the making,
SHOOTOUT is purely graphical combining arcade excitement with just the
right touch of strategy.
Cassette for TRS-80" Color (16K): $20.00

VOYAGER

A solitaire science fiction game that challenges you to explore the four levels
of an alien spacecraft's maze-like corridors and rooms in 3-D simulated
graphics, all the while avoiding robots programmed to blast any intruders. In
order to win, you must destroy all power generators and escape or hunt out
and annihilate all of the killer robots. VOYAGER comes with color-
animated graphics and sound capabilities for computers so equipped.
Cassette for TRS-80" Color (16K): S20.00

MIDWAY CAMPAIGN

Your computer controls a huge force of Japanese ships whose objective is to
invade and capture Midway Island in this tense wargame. In the actual
engagement, the Japanese made several tactical errors which cost them the
battle. Your computer probably won't make the same mistakes! You com-
mand the badly out-numbered and outranged U.S. Naval Forces. Your only
advantage is surprise.

BREAKTHRU (in 3-D)

Don't take our word for it! Here's what Color Computer magazine has
to say: "This is truly a good game". Short and sweet as this description
may be, BREAKTHRU is really much more than just a truly good game!
It's a combination of racquet and WALLBALL. The object is to knockout
five consecutive walls at the opposite end of the court using a joystick
paddle to strike or deflect the lively ball. BREAKTHRU is written in pure
machine language to give you a fast-action, three-dimensional, high-
resolution sports experience for hundreds, maybe even thousands of hours
of entertainment.
Cassette for TRS-80* Color (16K): S20.00

v.c.

V.C. (short for Viet Cong) is Avalon Hill's first wargame on the controversial
Viet Nam War. Under your command is the chopper based air-mobile and
heavily armed 1 /509th Air Cavalry and 9/ 15th Field Artillery for fire sup-
port. It is an unconventional conflict. You have the task of bringing the
civilian population under your protection where the enemy can hide amongst
the people, and where the politics of terrorism and friendship can turn the
people you want to save against you. V.C. faithfully re-creates this struggle
in which you can lose without ever being defeated.

A DIFFERENT STANCE

Editor:

Your stand against software piracy is
admirable and some of the measures that
you have taken will surely have a positive
effect, but 1 think you are off the track on
one point. Specifically, your request that all
tape copy utilities be removed from the
market. This type of utility is essential for
anyone that is trying to manage a reasonably
large tape-based software library. Besides,
anyone that is skilled enough to write a valu-
able program could easily protect it against a
general purpose tape copy utility. I have
written and marketed a utility program that.
among other things, will, as advertised, copy
"virtually" any program. The reason that I
was able to do this was. up until now any-
way, "virtually" all software for the Color
Computer is minimally protected. A far
more damaging program, which I would not
advocate removing from the market, is the
disassembler. Although it is very easy to
defeat a general purpose copy utility. I chal-
lenge anyone to encrypt a program such that
I could not "break" it with the help of a
disassembler.

In my opinion, your stand on this particu-
lar issue will be more damaging than benefi-
cial to the CoCp community.

Darrel Price
DP Development

Editor:

In the letters to Rainbow column of the
December issue there is a letter from Ron
Krebs of Mark Data Products. In the letter.
Mr. Krebs stales that none of their software
is protected.

Well. Mr. Krebs, I own tape copies of
both your Astro Blast and your Color Hay-
wire programs and they are both autoexecu-
ting with no way to back them up or convert
them to disk.

If this is not protected, then what do vou
call it?

Marlin Simmons
Bridgewater. VA

Editor:

I have been following the controversy
about piracy in your maga/ine with some
interest. As a software producer I am inter-
ested in both a personal and professional
way, and when I chose to publish Omni-
Clonemd Clone-Master 1 made it clear that
I believe the consumer has a right to make
backup copies of their tapes and disks to
prevent loss.

Nevertheless, I have seen several letters
from consumers that seem to make the same
point (the latest was in your December
issue), and I must respond.

The premise of these letters seems to be
that commercial software for the Color
Computer is overpriced, and thus it is fair
game for the pirates. To quote one letter:
" . . .and another firm puts out a lousy pro-
gram for SI 7.95. so who is the pirate?"

frankly. I tind this entire premise to be so
much throughput from male cows. 1 person-
ally think that new cars are high in price, but
that certainly gives me no right to steal them!
It amazes me that anyone could even suggest
such an idea.

As consumers you have the final power in
this market, but it isn't the power to steal and
then justify it with some self-righteous gob-
bledygook. It*s quite simple. If 1 think the
cars are too expensive. I am free to not buy
them, and as a merchant. I am free to price
my products however I like. If someone
thinks a program is too expensive, they are
free to keep their money in their wallet. If
you think differently, try shoplifting some-
thing from a high priced store in your area,
and then tell the judge it was okay, because
the stuff was overpriced anyway. No, that's
just not how' it works. But. as the man said in
the last line of his letter, "everyone wants an
alibi."

Thank you for the excellent quality maga-
zine you are publishing. It gets better with
every issue. I would like to suggest that you
publish more articles on the fundamentals of
machine language programming. Many of
the articles involving this type of program-
ming are hard for me to understand, proba-
bly because I don't know what's going on.
Paul Cournover

Editor:

Thank you for publishing a truly informa-
tive and excellent magazine. Please keep up
the articles on assembly language, and the
hardware articles. There should be at least
one, maybe two or three hardware articles
each month in Rainbow. I will try to eventu-
ally contribute some ideas or articles myself.

HOW DOES NIDA SPELL RELIEF?

Editor:

Relief can also be spelled FRAYSSE, for
allowing himself to be on call when uncoor-
dinated fingers fumble through his Mara-
thon. And what a game That is! I'm too old
and slow to play and succeed, but my kid
plays it with POKE 65465.0 although he
occasionally slightly decreases speed by press-
ing the fire button.

I will continue to read Rainbow in hopes
of learning all things wonderful, including
what is a "bubble sort": "screen
dump": "concatenate'".'

Nida Lewis
Eollett. TX

Editor:

I find your magazine very interesting and
useful. The balance of software, hardware
and tutorial articles is excellent! The contin-
uing good articles are strong evidence that
the CoCo is a powerful machine and a great
choice for home computing.

One program I really enjoyed was Rain-
how Roach by John Fraysse. 1 sent him a
tape and he promptly sent back a copy which
I found to be a super game. In fact a friend,
who is an Apple devotee and sold computers
for a while, was flabbergasted that such a
fast, High-Res program could be done on a
lowly CoCo. I'll be expecting to see more
articles from John.

Keep up the good work ! You have the best
CoCo magazine going!

BOUQUETS AND BRICKBATS

Editor:

I just received a defective keyboard (which
I'm sure does not occur very often). I sent it
hack for repair. The board was lost in
transit.

After one phone call we(H.S.L. Products
and I)cametoanagreement that they would
replace my keyboard and this wasjust on my
word that if they did not receive the board
and after the claim from our postal services
came across. I would send them the amount
of the claim (which might take up to six
months).

As far as I'm concerned. H.S.L. is top
notch in my book and I recommend their
services. As the saying goes "you learn some-
thing new everyday."

My lesson for today is there are still some
people who are honest, reliable and most of
all have respect for customer relations.

Again. H.S.L., thank you.

Richard Nam el
LaSalle. Quebec

Editor:

I'm not one to complain but in this case
I've just got to speak up. My "beef" has to do
with the advertisements I see in the Rainbow.

Now, I don't want you guys to stop using
pretty girls to catch the reader's attention,
but there are quite a few feminine fingers
flickering over the keyboard (me, for one)
and speaking for myself I wouldn't mind
seeing a nice looking young man touting
software, or hardware for that matter. A
good looking guy smiling over a disk drive
or. say. showing the maneuverability of a
joystick would catch my eye and ho\d my
attention at least long enough to find out
who the dealer is.

I really do think you produce one of the
best magazines for the CoCo around,
I really look forward to mine coming the
first part of every month, that is if the post-
man doesn't decide to read it lirst.

February 1984 the RAINBOW 13

PRINT #-2,

T!

this is our big Adventure Issue and it is a pretty auspi-
cious occasion for the Rainbow. First of all, this marks
the beginning of our Second Annual Adventure Contest
and the publication of the first book that Falsoft, Inc.. our
parent firm, has ever put out.

I was really pleased with the first Adventure Contest for
several reasons. First of all, it made us a lot of new friends, and
second, it brought some real quality programs to the Rainbow
and to you. And we expect that this year's contest will be much
the same — but, probably more so.

First prize in the Second Annual Rainbow Adventure Con-
test is a complete disk drive 0. including controller. This prize is
being offered by the Rainbow. Other prizes will be announced
next month but, this time around, everyone who enters gets a
bonus: A free three-day pass to the RAINBOWfestof his or her
choice. When you send in your entry, please specify which
RAINBOWfest you want your free ticket for.

The rules for the Second Annual Rainbow Adventure Con-
test are pretty much the same as last year. All programs become
the property of Falsoft, Inc., and none can be returned. By
entering the contest you warrant that the work is yours originally, and that you have the right to offer it
as yours. Winners will be notified by mail and telephone, so please make sure we have both your address
and telephone number.

Finally, there is the deadline. All entries must be postmarked on or before May 1. 1984. (We have
extended our March I deadline that we previously announced.) Also, entries must be submitted on
magnetic media — disk or cassette. Please be sure to give us complete loading instructions and, as you
feel necessary, give us plenty of information on the game. Also, for the purposes of judging, please give
us the answer to the program. I n order to properly judge the contest, we have to know how a player can
win and what happens when he or she does.

Secondly, as you read this. The Rainbow Book of Adventures is available. You might check your
local store that carries the Rainbow to see if they have it in stock. If not, you can order it from us or from
several of the mail order firms which we anticipate will be advertising it. Cost of the book is S7.95
(Kentucky residents please add sales tax if you order from us). A tape version of the Adventures is $8
and, yes, just like Rainbow On Tape, you must have the book to get the instructions on how to load and
run the programs on the tape.

We think both are a bargain. We've tried to keep the price low in order to make it as affordable as
possible. There are 14 programs in the book and on the tape and the book is an attractive 100-plus pages
with nice artwork, a four-color cover and a true "spine," just like the Rainbow itself.

I'm really proud that we have been able to publish this, our first book. More will be coming. And, it
would be very inappropriate to mention The Rainbow Book Of Ac/ventures without mentioning the
names of Susan Remini and Peggy Henry, the editorial and art directors for this project. Both of them
worked long and hard extra hours and arc justifiably proud of what they have accomplished.
And we're proud to be able to bring it to you!

By the time you read this, RAINBOWfest will be close at hand in Long Beach. California. I believe it
is going to be a great show, but I told you a lot about that a month ago so I won't repeat myself here.

However, we have some extra special things which havejust come togetherthat I think will add a little
icing on the cake to this RAINBOWfest that will make it even more worth your while to come.

First. Phil Kitchen, who runs the Third Party Software Support operation for Radio Shack will be
conducting a special seminar during the show. As you may know. Radio Shack has a program which
helps software authors and Phil will be explaining the program at length. It will also give you an
opportunity to ask questions concerning Third Party Support. It is a must if you are in the software
business, or have any interest in becoming involved.

Second, Radio Shack will be conducting a show-long class on computing and CoCo during
RAINBOWfest. Here's a great chance for some extra hands-on instruction about CoCo and. too. here
is an opportunity for you to "turn on" a friend, neighbor, child or spouse to the wonderful world of
CoCo. Admission to the classroom is included with your admission to RAINBOWfest itself.

All that, plus the best single Color Computer show ever held, makes Long Beach look great. 1 hope to
see you there!

THE ORIGINAL

Simply slated, Telewriter is the most powerful
word processor you can buy for the TRS-80
Color Computer. The original Telewriter has
received rave reviews in every major Color
Computer and TRS-80 magazine, as well as
enthusiastic praise from thousands of satisfied
owners. And rightly so.

The standard Color Computer display of 32
characters by 16 lines without lower case is
simply inadequate for serious word processing.
The checkerboard letters and tiny lines give you
no feel for how your writing looks or reads.
Telewriter gives the Color Computer a 51
column by 24 line screen display with true
lower case characters. So a Telewriter screen
looks like a printed page, with a good chunk of
text on screen at one time. In fact, more on
screen text than you'd get with Apple II, Atari,
Tl, Vic or TRS-80 Model III.

On top of that, the sophisticated Telewriter
full-screen editor is so simple to use, it makes
writing fun. With single-letter mnemonic
commands, and menu-driven I/O and
formatting, Telewriter surpasses all others for
user friendliness and pure power.

Telewriter's chain printing feature means that
the size of your text is never limited by the
amount of memory you have, and Telewriter's
advanced cassette handler gives you a powerful
word processor without the major additional
cost of a disk.

TELEWRITER-64

Bui now we've added more power to
Telewriter. Not just bells and whistles, but
major features that give you total control over
your writing. We call this new supercharged
version Telewriter-64. For two reasons.

64K COMPATIBLE

Telewriter-64 runs fully in any Color Computer
— 16K, 32K, or 64K, with or without Extended
Basic, with disk or cassette or both. It
automatically configures itself to take optimum
advantage of all available memory. That means
that when you upgrade your memory, the
Tclewriter-64 text buffer grows accordingly. In
a 64K cassette based system, for example, you
get about 40K of memory to store text. So you
don't need disk or FLEX to put all your 64K
to work immediately.

64 COLUMNS (AND 85!)

Besides the original 51 column screen,
Telewriter-64 now gives you 2 additional high-
density displays: 64 x 24 and 85 x 24!! Both
high density modes provide all the standard
Telewriter editing capabilities, and you can
switch instantly to any of the 3 formats with a
single control key command.
The 51 x 24 display is clear and crisp on the
screen. The two high density modes are more
crowded and less easily readable, but they are
perfect for showing you the exact layout of
your printed page, all on the screen at one
time. Compare this with cumbersome
"windows" that show you only fragments at a
time and don't even allow editing.

RIGHT JUSTIFICATION &
HYPHENATION

One outstanding advantage of the full-width
screen display is that you can now set the
screen width to match the width of your
printed page, so that "what you see is what
you get." This makes exact alignment of
columns possible and it makes hyphenation
simple.

Since short lines are the reason for the large
spaces often found in standard right justified
text, and since hyphenation is the most
effective way to eliminate short lines,
Telewriter-64 can now promise you some of the
best looking right justification you can get on
the Color Computer.

FEATURES & SPECIFICATIONS:

Printing and formatting: Drives any printer
{LPVH/VIII, DMP-100/200, Epson, Okidata,
Centronics, NEC, C. Itoh, Smith-Corona,
Terminet, etc).

Embedded control codes give full dynamic access to
intelligent printer features like: underlining,
subscript, superscript, variable font and type size, dot-
graphics, etc.

Dynamic (embedded) format controls for: top,
bottom, and left margins; line length, lines per page,
line spacing, new page, change page numbering,
conditional new page, enable/disable justification.
Menu-driven control of these parameters, as well as:
pause at page bottom, page numbering, baud rate (so
you can run your printer at top speed), and Epson
font. "Typewriter" feature sends typed lines directly
to your printer, and Direct mode sends control codes
right from the keyboard. Special Epson driver
simplifies use with MX-80.

Supports single and multi-line headers and automatic
centering. Print or save all or any section of the text
buffer. Chain print any number of files from cassette
or disk.

File and I/O Features: ASCII format files —
create and edit BASIC, Assembly, Pascal, and C
programs. Smart Terminal files (for uploading or
downloading), even text files from other word
processors. Compatible with spelling checkers (like
Spell 'n Fix).

Cassette verify command for sure saves. Cassette auto-
retry means you type a load command only once no
matter where you arc in the tape.
Read in, save, partial save, and append files with disk
and/or cassette. For disk: print directory with free
space to screen or printer, kill and rename files, set
default drive. Easily customized to the number of
drives in the system.

Editing features: Fast, full-screen editor with
wordwrap, block copy, block move, block delete, line
delete, global search and replace (or delete), wild card
search, fast auto-repeat cursor, fast scrolling, cursor
up, down, right, left, begin line, end line, top of text,
bottom of text; page forward, page backward, align
text, labs, choice of buff or green background,
complete error protection, line counter, word counter,
space left, current file name, default drive in effect,
set line length on screen.

Insert or delete text anywhere on the screen without
changing "modes." This fast "free-form" editor
provides maximum case of use. Everything you do
appears immediately on the screen in front of you.
Commands require only a single key or a single key
plus CLEAR.

. . . inity a state of the art word processor. . .
outstanding in every respect.

BUILDING FEBRUARYS RAINBO

Our Adventure Issue . . .

Basketball to Image Processing . . .
And, Introducing Rainbow Tech .

Yes, it's Adventure Contest time again and we not only have plenty of
prizes for our Second Annual Rainbow Adventure Contest, but we also
have several tutorials to get you started and some sample programs for you
to learn from — including Karrak, a special lour-part Adventure written by one of
last year's top contest winners, Gregory Clark. The contest deadline for entries is
May I, 1 984. and we'll award prizes in all sorts of categories so, even if you're a
novice Adventurer, you have plenty of time to develop an entry.

Check out Captain 80's column for his "Adventuring in Style" commentary,
and also read Liddil's tutorial on how to create a winning Adventure. Then, Eric
Tilenius will provide an excellent short course in Adventure programming as he
walks you through the creation of his Mini Adventure. For still more, head for the
jungle in search of King Merro's crown in Jeff Craig's Adventure. And. when you
begin Karrak, take my advice: Don't mess with the turtle.

Back issues of the Rainbow have many other Adventures and Adventure
tutorials if you want to learn more before you try your hand and, yes. The
Rainbow Book of Adventures is a reality. 1 12 pages of winning programs from
last year's contest. It's $7.95 and, if you can't find it at your computer store, call or
write us — and ask about the Rainbow Adventure Tape ($8). too.

Adventure and more. How about golf? Mike Knolhoffoffersusan invitation to
"The CoCo Open" in one of several games in this issue. On the more serious side.
Dr. Bob Tyson, winner of our recent simulation contest, delves into "image
processing," a technique used to enhance pictures sent back by space probes.

Both the game and the statistical sides of basketball come into play in this issue
as Gary L. Carter offers a sports simulation and Dick White gives us a computer
program to keep up with all the game stats from your favorite teams.

Making its debut this month is "School is in the Heart of A Child," by longtime
Rainbow columnist Bob Albrecht and his new co-author Fran Saito. We welcome
this series for the parents of very young children with the expectation that it will be
as big a success as Bob's continuing scries, the "GameMaster's Apprentice."

Also new this month is Rainbow Check Plus, by H. Allen Curtis. Allen offers us
a markedly improved version of our familiar Rainbow Check program begun in
January 1 983. Th is month, values for both our old checksum program and Allen's
new one appear in the "checkboxes" at the beginning of each listing, but next
month we will begin using this new version exclusively.

Still another addition is RainbowTech, a special section for the more techni-
cally minded. While it is by no means forbidden territory for the beginner, we are
putlingsome of our more advanced features in this portion of the magazine. Dale
Puckett's "KISSable OS-9" will be a regular RainbowTech column. And Rain-
bow Technical Editor Dan Downard — we call him Dan Landers around these
parts — will answer your technical questions in his new monthly Q & A feature.
"Downloads."

Joining us this month and rounding out the faculty of RainbowTech are two
CoCo community celebrities, Frank Hogg and PaulSearby. Frank will be writing
about advanced operating systems, including OS-9. FLEX and 64K topics while
Paul launches a regular feature on the design and development of application
software for the CoCo.

No, we aren't offering advanced degrees from RainbowTech. but we do think
there is much thai can be learned by reading the Rainbow, and the tuition is very
reasonable: For just $28, you get a full year's worth of educational material at a
rate of more than a dozen pages a day. So, if your name's not yet on the roster, why
not enroll and keep the Adventure going all year 'round.

CHECK PLUS

FOR THE

AND THE

MC-IO

By H. Allen Curtis

Since the January 1983 issue, the Rainbow has pro-
vided you with a program. Rainbow Check, to ease
the labor of your typing its BASIC programs. Rainbow
Check was the means of determining a class of typing errors
that would change the byte count of a specified number of
lines of BASIC programming.

There were some important classes of typing errors that
Rainbow Check could not detect:

1 ) It could not distinguish between incorrect and correct
line numbers, such as 300 CLS from an intended 390
CLS.

2) It could not distinguish between incorrect and correct
variables, such as F from an intended E.

3) It could not distinguish between incorrect and correct
command words, such as SIN from an intended SGN.

For your further convenience a new, more comprehensive
checking program, called Rainbow Check Plus, has been
developed. It will detect errors of the classes 1 ), 2) and 3) as
well as the class detected by Rainbow Check. There are two

(H. Allen Curtis, who earned degrees from the College
of William and Mary. M.I.T., and Harvard, recently
won an award for meritorious service from the IEEE
Computer Society. He has had published a college
reference book in the computer science field, as well as
many papers and articles.)

versions of Rainbow Check Plus — one for CoCo users and
another for MC-IO users.

The BASIC interpreter puts every program into the follow-
ing form: Every number initiating a line of BASIC program-
ming is represented by two bytes — a most significant byte
and a least significant byte. Every command word is repres-
ented by a token byte. In the case of CoCo some command
words are represented by 2-byte tokens. Each character,
other than those comprising command words, is represented
by a single byte in ASCII code.

Rainbow Check Plus includes each of the aforementioned
bytes in the calculation of checksums. In those calculations
Rainbow Check Plus employs a number system in which the
successor of 255 is 0.

When you erroneously type 300 CLS when 390 CLS was
intended. Rainbow Check Plus uses the bytes I and 44.
instead of the correct byte values I and 134. in calculating
the checksum. The ensuing incorrect checksum indicates
that a typing error has occurred.

Similarly, when F is mistakenly typed for E, the ASCII
code 70 is used instead of the correct code 69 in checksum
calculations.

II a typed character is part of a valid BASIC command
word, the value of the token used by the basic interpreter to
represent that word is associated with all the characters in
the word. For example, the value associated with F, Oand R

of FOR would be 128. the token representing FOR in both
CoCoand MC-10.

Suppose that you mistakenly typed SIN when SGN was
intended. In CoCo, the token for SIN consists of two bytes
whose values are 255 and 132. These values would be
employed in checksum calculations instead of the correct
ones, 255 and 128, for SGN. In MC-10, the SIN token, 185.
would be used instead of the correct value, 177.

Thus, it is seen that for every error you make in typing a
BASIC program, an incorrect byte value is employed in the
Rainbow Check Plus checksum calculations.

The Listings 1 and 2 show CoCo and MC-10 versions,
respectively, of Rainbow Check Plus. It is part BASIC and
part machine language. The BASIC part generates the
machine language part which does the actual checking. The
BASIC portion stores the machine language program at the
78 and 91 highest RAM addresses of CoCo and MC-10,
respectively. Regardless of whet her your CoCo isa4K, I6K
or32K RAM system, the machine language program will be
stored in high RAM. The former Rainbow Check did not
support 4K CoCo systems.

You use Rainbow Check Plus as follows: Suppose you
wish to type from the Rainbow a BASIC program having a
Rainbow Check Plus box such as:

765.... 229
1600.... 37
END.... 184

With the machine language program stored in high RAM
as a result of running Rainbow Check Plus (do not run the
BASIC part more than once), type NEW and press [ENTER],
Then type all lines up to and including Line 765 of the
Rainbow program. Next, press the down-arrow key of your
computer. A decimal checksum will immediately be printed
on the screen. It should be 229. If it is not, you have made a
typing error. When you have correctly typed in all lines

To achieve 19200 Baud, one must use the pokes for 9600
Baud and then use the bold poke (65497,0) to double the
CoCo's speed. (Use POKE65496.0 to restore normal speed.)

through 765. type all lines from 765 through 1600. Again
press the down-arrow to display the next checksum. It
should be 37. if your typing was correct. When you have all
lines throuh 1 600 correctly typed, finish typing the program.
Then, pressing the down-arrow should display the number
184 if your typing has been perfect.

It should be pointed out that your typing accuracy can be
further facilitated if you take advantage of the following
fact: the Rainbow duplicates your computer's 32-character
per screen line format in its presentation of BASIC programs.
This makes it easy to discover whether or not your typing is
properly spaced.

RAINBOW

Of Meddo

By Jeff Craig

I was first introduced to Adventures on the TRS-80
Model III and it wasn't until I got a CoCo, a year later,
that I actually started playing Adventures. At first it was
pretty confusing, but after awhile I got the hang of it and I
started solving them. I thought then and 1 still think that
Adventures are great. I*d even go as far as to say that I like
Adventures better than most arcade-type games.

One day I sat down with my computer and began to make
a two-word Adventure. 1 soon found out that it wasn't as
easy as 1 thought! 1 wanted to find a way of identifying the
words entered without using a whole bunch of LEFTS and
RIGHTS garble. After a few days of searching and thinking,
1 found the long-lost INSTR command. With some help
from my dad, who is also a CoCo enthusiast, I created a
faster and shorter subroutine than other Adventures. In this
program, the INSTR command compares the words entered
with those in the program's vocabulary and converts the
words into numbers. If the word is not in the vocabulary,
then the number will come out as 0. Another thing that I
think is pretty nifty is my scrolling routine. It's not really
part ol'the the Adventure, but 1 think it adds spice. To scroll
the phrase across the screen, I used FOR loops and LEFTS,
RIGHTS. You can change this subroutine and use it in
different programs.

As in most Adventures, Metro has a main objective. Your
mission is to find the ancient crown of King Merro. which is
hidden somewhere in the Amazon jungle. Be careful, there
are many hazards to face in the jungle!

This Adventure recognizes commands such as GET.
LOOK, N to go north, and even GO as in GO RIVER. The
vocabulary does not contain different words that mean the
same thing, such as EXAMINE and LOOK, so if one word
doesn't work, try another, 1 have not incorporated a save
feature in this game because I didn't really find it necessary,
but if you find otherwise, I am sorry. I don't have any hints
for you because I don't want to make it any easier for you
(hee hee).

This game takes almost all of my 16K so it is necessary to
type in PO KE 25,6: NEW before you load it or finish typing
it in. Also, it is necessary to unplug your disk drive when
RUNning.

February 1984 the RAINBOW 27

I hope you enjoy playing this game. If you require any
assistance in solving it, please write: Jeff Craig, 2556 James
Ave., Muskegon. Mich., 49442. Good luck!

(Jeff Craig is a sophomore and honor student at Mus-
kegon, Michigan 's. Orchard View High School. He is
interested in science fiction and role playing games. In
the future, he hopes to attend the Air Force Academy
and major in aviation or computer science.)

Creating the
Well-Blended Adventure

TltoSH,

By Eric W. Tilenius

^

\h07

Are you tired of trying to write "Munch Man" in
BASIC and having it turn out as "Mush Man"?
Turn your creativity to something more reward-
ing—creating ADVENTURES.

This article will show you how you can design your
own Adventures in basic. As an example, a Miniventure
will be built step-by-step. 1 call it a Miniventure since it is
very small (9 rooms), but contains all the elements you
find in most larger adventures.

With a good imagination and your trusty Color Com-
puter, you will soon be on the road to . . . Adventures!

The first step in creating an Adventure program is to
come up with a scenario, or setting, for the Adven-
ture. The scenario should give a background to the

(Eric W. Tilenius is a sophomore at Walt Whitman
High School and has been programming and working
with computers for several years. He is currently serv-
ing as an advisor and consultant to people new to the
computer field. During his freshman year, Eric was
editor of The Stinson Stylus, a school newspaper.)

Adventure as well as provide the Adventurer with a main
goal to accomplish. Some examples of scenarios are:

• The Adventurer is trapped in an old haunted house. He
must search for a lost treasure and find a way out, while
avoiding the ghosts, monsters, and other assorted hazards
that await him within.

• The Adventurer is on an intergalactic spaceship when
it is attacked by hostile enemies. He takes a small shuttle-
craft and flees from the ship just before it is destroyed by
the enemy. The shuttlecraft, however, runs out of fuel
before it can get him to the nearby space station. It crash
lands on a nearby planet and is almost totally destroyed
by the crash. The Adventurer must now deal with possi-
bly hostile aliens and the many other dangers of the alien
environment and try to get off the planet and back to the
space station.

• The player lives in a realm of magic and sorcery. He
must defeat enemy wizards, battle fierce dragons, and
outwit many other creatures in an attempt to rescue a
captive princess.

INTERCEPT 4

By J. Weaver, Jr.

Your ship and the planet are under attack. Hostile alien craft whip around
the ship, releasing flamming bolts of energy upon the hull of the INTER-
CEPT. Immediately your own guns come alive, warding off the sudden
attackers, but will it be enough? Already many of the fighters have escaped
past your ship toward the defenseless colonies below. Once the air battle is
over, you must transport down to the planet, try to find the alien foe, and
destroy them. Then, the hardest task awaits: Using the full power of the
INTERCEPT, you must battle and destroy the mother ship!! Three separate

screens or levels of play. Each screen scrolls in all four directions. A fantastic new game by the author of Outhouse. Requires two
joysticks. 32K $27.95/29.95

GRAPHICOM

The hit of the Pasadena Color Expo. The greatest graphics
program to ever be written for the COCO. Graphicom was
over two years in the making! Graphicom uses two joysticks
or one joystick and one kola pad. The program uses rubber-
band graphics and unique method of making stamps and
using colors. Each screen is saved on a special disk. When
you call up a directory it comes up in pictures to show you
what is on the disk.

Graphicom can screen dump graphics to over 20 different
printers! Graphicom can send pictures over the modem!
Graphicom can reverse the video, rotate pictures, and make
mirror images. Graphicom can do more than any other
graphics program and its only $29.95.

• The player is a private detective who one day receives
an anonymous phone call saying that terrorists have
planted a powerful bomb in the center of L. A. He tries to
tell the police about this but no one listens. He must
discover the bomb's location on his own and deactivate it
before it is too late.

As you can see from the examples above, the scenario
can be set just about anywhere — real or fictional - but
there are a few general rules which should be applied in
creating a scenario. First of all. it should be large enough
to give the player plenty of room to move about. An
Adventure set in Joe's Auto Garage just won't work.
Secondly, it should provide the Adventurer with one
main goal (finding treasures, for example). Lastly, it
should lend itself to the creation of puzzles and obstacles
which the Adventurer has to solve. Remember: the more
imaginative and creative the scenario, the more fun the
Adventure will be to play.

The second step in creating an Adventure is the forma-
tion of puzzles and obstacles which the Adventurer must
solve and overcome in order to achieve his main goal.
You can often gel ideas for good puzzles by playing other
adventures, but the best puzzles are those that arc both
original and logical. Obstacles include anything that the
player must "physically" overcome (as opposed to puz-
zles, which are solved mentally) and include anything
from locked doors to wandering monsters. Try to think
up as many of these as you can that would go with your
scenario, and then select those that you think are best.
For example, if your scenario was similar to the one with
the spaceship above, you might think up some puzzles
and obstacles such as these:

• Aliens surround the Adventurer and gesture menac-
ingly at him. He must get past them somehow without
arousing their anger.

• The Adventurer must obtain a golden disk in order to
enter the walled city of the ancients.

• Once inside the city of the ancients, he must decipher
the old scrolls of knowledge which tell where things that
he needs are hidden.

MAPPING IT OUT

Up to now, all you have done is to think about what
your scenario would be, and what puzzles and
obstacles you could use in such a scenario. Now, how-
ever, we begin the "drawing up" of the main part of the
Adventure itself.

An Adventure is divided into many locations called
rooms. A room can be anything from a closet to a forest.
It may have one or more objects in it and may have exits
in any of four directions — north, south, cast, or west.
(Some adventures use up and down also.) When the
player enters a room, the computer tells him the above
information. Here is an example:

YOU ARE IN A SMALL ALCOVE

YOU SEE: HAMMER SHOVEL

OBVIOUS EXITS LEAD: EAST WEST

What you have to do now is to create and map out
rooms in your Adventure. Take a large piece of paper and
draw boxes on it — as manv boxes as there are rooms in

your Adventure. If you are not sure how many rooms you
will have, start with several boxes and leave room to add
on. Each box will represent one room in the Adventure.
Now, number each box starting with U I then 2 then 3, etc.
... Do not skip numbers! It docs not matter what box
gets what number, or even if the numbers are in order
—only that each box has its own number. It is a good idea
to put each number in a corner of the box so that there is
room in the box for other things which we will add
shortly. Each room in the Adventure will be identified to
the computer by the number which you have put in the
box.

Now give each room a name and list what, if any,
objects are in it. You must also indicate the exits using the
following procedure:

1. Connect "rooms" (boxes) that lead to one another by
drawing a line from one to another.

2. If one room leads to another but is blocked (by a door,
for example), draw a line but mark on that line whatever
is blocking it.

If you are a little confused, see Diagram I. It should
help to clear things up.

DIAGRAM I: An example of a map of an Adventure.
Each room is given a number which appears in the top of
each box. The room name is on the top, and visible
objects are listed on the bottom of the boxes. Paths
leading from one room to another are marked (by an mm).
Note the blockage between rooms 4 and 7. Please keep in
mind that this is a scaled down map — you will probably
have more rooms than this.

Try to incorporate the puzzles and obstacles which you
have thought up into the map. For example, in the sam-
ple map, the Adventurer must find a way to get over the
high wall. Also, in order to get the oil. he must first get the
bucket.

Once you have done this and completed your map, you
are ready to . . .

START PROGRAMMING

So far. your CoCo might have just as well been a flower
stand. We haven't even touched it! But now let's
change all that. Put your map down by your computer,
power it up, and get ready to go\

36

the RAINBOW February 1984

The first step is to get CoCo to
remember a "map" of your Adven-
ture. This is done by putting it into
DA TA statements and then read-
ing it into ARRAYS. (In case
you're a little rusty on your arrays,
see chapters 20 & 21 in "Getting
Started with Color BASIC." To
review READ and DATA see
Pages 94—100 & 127 in the same
book.)

Start your program at about
line 100. Type in the room names
as DATA, going in order accord-
ing to the room numbers. So, for
the map above, you would type:

100 DATA LANDING SITE,
ENTRANCE TO ALIEN CITY,
LIGHTBRIDGE.DESERTED
PLAIN.ANCIENT TEMPLE,
COMPUTER BUILDING.C1TY
OF THEANCIENTS,STORAGE
BUILDING, OIL REFINERY

You will probably need more
than one program line to do this.
Next, type in the data for the
objects using this format: LONG
OBJECT NAME, SHORT OB-
JECT NAME, ROOM where ob-
ject is at start of the Adventure.
The long object name is a descrip-
tion of the object, such as is on the
map. The short object name is one
word which the person can use if
he wants to TAKE the object.
(For example, to take the golden
disk, a person would say "TAKE
DISK".) If the object can not be
taken (a spaceship, for instance)
type an * instead of a short object
name. For the objects on the sam-
ple map, you would type in:

200 DATA WRECKED SPACE
SHIP,*, I, GOLDEN DISK,
D1SK,2„ALTAR,*,5, BOOK,
BOOK.5, LASER GUN, GUN.4,
ADVANCED COMPUTERS,*,
6.01L,* ,9,BUCKET,8, WRITING
ON THE WALL,* ,7

The next step is to create what is
known as a travel table. The travel
table tells what room the player
will be in if he moves in one of the
four directions. Its format is:
NORTH,SOUTH,EAST,WEST—
each of which represents the num-
ber of the room the player would
get to if he moved in that direc-
tion. If the player cannot move in
a certain direction, a zero (0) would

TIME BANDIT

This month is the first month that the entire top ten panel had copies of Time Bandit and
they overwhelmingly voted it into first place. Never before has a game received so many
first place votes. At the Dallas Rainbowfest and at the Pasadena Color Expo, arcade
players were unanimous in the praise of Time Bandit. "The best original game ever
written for the COCO'" . . . "My dad said I could buy only one game and this is the best
game here"... "Best game at the show".. . "Best game I've ever seen on a home
computer" . . . "Great Game" . . . Only game I bought at the show" . . . These are comments
we heard about Time Bandit at these two shows ... I can say without a doubt that TIME
BANDIT is the best game on the market for the COCO.

be placed under that direction. If the Adventurer dies by
going in that direction, a 1000 would be placed in that
direction. If the direction is blocked, a negative number
would be placed for that direction. Each room has its own
data entry for this, as seen in the travel table for the
sample map listed below:

300 DATA 0,4,0,0 :REM GOING SOUTH LEADS

BLOCKED

370 DATA 0,0,9,7

380 DATA 0,0,0,8

You can make up a list of obstructions and create a
value for each. For example: -1 if a wall is blocking the
way, -2 if a door is in the way, -3 if a monster blocks the
way, etc. . . .

Next, type in the commands (verbs) which you wish
your Adventure to recognize. Next to each verb, place a
VERB NUMBER. If two verbs are the same (e.g. GET
and TAKE) place the same number for each. Use low
numbers as it will make things easier for you. These
numbers will be used to identify the verbs later on. A

common verb listing is:

400 DATA TAKE, 1, GET ,1, DROP, 2, GO,3. LOOK.4,
READ.4, MOVE.5, PUSH.5. PULL.5, UNLOCK.6,
OPEN/7, INVENTORY.8

Now that you have all your data statements in, we can
proceed with the rest of the program. The next thing we
are going to do is to READ all of the data into arrays so
that we can use it during the game. First we must DI Men-
sion the arrays which we will be using. L$ will stand for
the LOCATION and will be used to hold the room
names. LOS will be used for LONG OBJECT descrip-
tions, OS for the short OBJECT names, and O for the
room the object is in. C$ will be for the COMMANDS,
and C for the COMMAND numbers. T will be a two
dimensional array in which the TRAVEL table will be
stored. DIMension them at the start of the program by
typing:

10 DIM L$(X+l),LOS(Y+l)O$(Y+I),C$(20),T(4,X),
C(20)

Replace X in the above statement with the number of
rooms you have and replace Y with the number of objects
you have. DIMensioning the variables to X+l and Y+l
leaves room to add objects in later.

Now we can read the data ... To read the rooms, type:
600 FOR C=l TO X:READ L$(C):NEXT C. Simple
enough? Just remember to replace X with the number of
rooms that you have.

Now for the objects. Type the following, replacing Y

850 T$(l)="NORTH" :T$(2) =
"SOUTH": TS(3)= "EAST":T$
(4)="WEST"

Finally, let's string up the com-
mands and command numbers.
Count up how many commands
you have and replace N in the
statement below with that number.

Now that you have taken care
of all your DA TA,tt\l the compu-

off in by typing: 950 L=R. Re-
place R with a room number.

YOU DID IT. All the data is
now ready to be used.

MAKE IT WORK

Data is no good if it is not used,
so let's proceed to use it. The
first thing the adventure should do
is tell the player about his sur-
roundings: the room he is in, vis-
ible objects, and visible exits. This
is accomplished by these lines.
Substitute the number of rooms
you have for Y.

If you have more obstacles, assign them a negative
number and put them in their appropriate place in the
travel table, and add on lines like the ones above.

Now that you have told the player about his surround-
ings, the next step is to ask him what he would like to do.

1 100 PRINP'WHAT WOULD YOU LIKE TO DO
NOW":INPUT AS

Most Adventures use the two-word commands, so that
is the system we will adopt for now. The first word that
the player types in should be one of the commands that
you entered into the computer before. If so. we represent
that word by its COM M AND NUMBER which you type
after the verb in the DATA statement. If the first word in
the player's command is not in the command list, we will
tell the computer to print a message saying so. This
procedure is listed below.

1 199 REM FIND THE FIRST WORD TYPED IN
(UP TO THE SPACE) AND CALL IT AIS

1200 FOR C=l TOLEN(AS):IFMID$(A$.C.I)=" "
THEN (AIS)=LEFT$(AS.C-I): B$=MIDS*A$,

C+1,LEN(A$)-C): GOTO 1230 ELSE NEXT
1210 AI$=A$:REM ONE WORD COMMAND

SUCH AS LOOK
1230 FOR C=l TO N :REM N = NUMBER OF

COMMANDS YOU HAVE IN VERB LIST
1240 IF C$(C)=AI$ THEN A=C(C):GOTO 1400:

REM IF VERB IS IN COMMAND LIST

THEN GOTO 1400
1250 NEXTC
1260 PRINT" I DO NOT UNDERSTAND THE

VERB":GOTO 1100: REM GO BACK TO

INPUT STATEMENT

That, long as it may seem, is one of the fastest ways to
sort through a command input. The verb which the
player typed in is known to the computer by its verb
number (stored as A) and if the player typed in two
words, such as GO SOUTH, the second word is stored as
B$. Line 1200 takes care of dividing AS into AlSand BS.
Lines 1230-1250 check to see if AIS is a recognized
command.

What good is all that? Well, now that we have torn AS
to bits and pieces, we can begin doing all sorts of things
such as . . .

MOVING AROUND

Now we tell the computer to GOTO various sections
of the program depending upon what command was
typed. Using the command ON. . . GOTO is the simplest
way to accomplish this.

1400 ON A GOTO 2000.3000.4000.5000.6000,7000.
8000,9000

This will send the program to line 2000 for verb #1
(GET or TAKE), line 3000 for verb #2 (DROP), line 4000
for verb #3 (GO), etc. . .

To get things moving, let's start with the routine for
GO at line 4000.

TAKING INVENTORY

Now that the player. can take things, he or she might
want to get a list of things being carried. This is done
by typing INVENTORY. Here is the'iNVENTORY ROU-

finds one equal to 1000 it prints that you have taken that

Too bad small shopkeepers don't have it this easy.

No Adventurer likes to carry around an armload of
junk, so he may want to get rid of unwanted objects or
objects that he no longer has use for. This procedure is
naturally enough called . . .

DROPPING OBJECTS

The drop routine, located at line 3000, checks to see if
the player has the object he wants to drop and. if he
does, it puts it in the room he is in by changing its object
number to the room number.

ANNOUNCING

The VIP Library™
With a Terrific Sale!

Nelson Software Systems is now Softlaw Corporation, under
new management. Our Super "Color" Library programs have
also undergone a name change. All programs are the same
unbeatable Super "Color" Library programs you've heard so
much about, but with new VIP names. To introduce our VIP
Library we are having a special sale on the following pages. Our
low prices for such high quality can't be beat so get started today!

Official Library of Software for the TANO Dragon

(Sold for the TANO Dragon only by TANO Microcomputer Products, Corp. and its distributors)

The Library Concept

State of the Art, Quality, Integrity,
Compatibility and Affordability. Five
things good software must possess.
Five things that epitomize the VIP
Library'". Each program is the
diamond of its class, true excellence.
These programs are first in features,
first in power, first in memory, and
all are affordably priced. And for
your convenience all disk programs
can be backed up.

State Of The Art

All Library programs are written in
machine code specifically for the
Color Computer, to work without
the interference of a separate
operating system such as FLEX. From
this comes speed and more work-
space for you. Unlike other programs
for the Color Computer which are
said to be 64K compatible, VIP
Library'" programs are not limited to
between 24 and 30K of workspace in
64K. Library programs have Memory
Sense with BANK SWITCHING to
fully use all 64K, thus giving up to
51 K with a disk version and up to
53K with a tape version.

Easy To Use

Each Library program was carefully
designed to be extremely easy to
use. Built-in on-screen help tables
are at your fingertips, as are menus
of all kinds. Every effort is made to
use logical, intuitive and easy-to-
remember commands. The manuals
have been thoughtfully prepared to
cover every aspect of the program,
and they have complete tutorials to
get you going right away. We set the
standard!

Lowercase Displays

State-of-the-Art graphics allow
instant use of four display colors, and
eight lowercase displays featuring
descending lowercase letters. You
can select from 51, 64 or 85 columns
by 21 or 24 lines per screen, with
wide or narrow characters in the 64
display. These screens provide a
pleasant and relaxing way to perform
your tasks, with as much text on the

". . . PICTURE getting your
instantaneous investment report
over the phone, using it in your
spreadsheet calculation,
generating a report, and writing
a memo including that report
and data from your database with
your word processor, and all this
with VIP Library 1 '' programs ..."

screen as is possible. Each program is
easy to learn and a joy to use. We
take pride in the stringent testing
done to make these programs per-
form flawlessly. Every feature, every
convenience, sleek, simple and
elegant.

Total Compatibility

All Library programs are
compatible. Transfer and use of files
between programs is easy and
carefree. What's better, when you
have learned one program the others
will come easy. And every program is
the best of its kind available.

The Library Programs

For your writing needs is the VIP
Writer'", and its spelling checker, the
VIP Speller"'. For financial planning
and mathematical calculations you
can use the VIP Calc". To manage
your information and send multiple
mailings there is the VIP Database'".
For sending all these files to and
from home or the office and for
talking to your friends you can have
the VIP Terminal". Finally, to fix
disks to keep all your Library files in
good repair we offer the VIP Disk-

Mini Disk Operating System

The Disk versions each have a Mini
Disk Operating System which will
masterfully handle from 1 to 4 drives.
It offers smooth operation for such
features as the ability to read a
directory, display free space on the
disk, kill files, save and automatically
verify files, and load, rename and
append files. Library programs simply
do not have the limitations of BASIC.

Professionalism

The Library comes handsomely
bound in gold-embossed, padded
leatherette binders to grace your
work area with the professionalism it
deserves. Welcome the VIP Library'"
into your home and office.

A description of each of the
Library programs, with the
special sale price, is contained
in the following pages. Please
indulge!

VIP Writer™

(Formerly Super "Color" Writer II)

By Tim Nelson

RATED TOPS IN RAINBOW, HOT COCO,

AND COLOR COMPUTER MAGAZINE

The Official Dragon Microcomputer Word Processor^

The most powerful and easy-to-use word processor is available in the
showpiece and workhorse of the Library: The VIP Writer™. Because of its
undisputed superiority over all Color Computer word processors, it was
selected by Dragon Data Ltd. of England and TANO in the U.S., to be the
Official Word Processor for their line of Dragon microcomputers.

The result of two years of research, the VIP Writer'" offers every
feature you could desire from a word processor. It is the most
powerful, fastest, most dependable and most versatile. With the hi-res
display, workspace and compatibility features built into the Library the
Writer is also the most usable.

", . . Nearly every feature and option possible to implement on the
Color Computer. The design of the program is excellent; the
programming is flawless . . . Features for the professional, yet it is easy
enough (or newcomers to master . . . Certainly one of the best word
processors available for any computer . . ." October 1983 "Rainbow"

"Word processing with VIP Writer is like driving a high-performance
vehicle . . . This Ferarri of a package has more features than Telewriter,
Easywriter (for the IBM PC), or Applewriter." October 1983 "Hot CoCo"

The Writer will work with you and your printer to do things you
always wanted to do. Every feature of your printer can be put to use,
every character set, every graphics capability at any baud rate, EVEN
PROPORTIONAL SPACING. All this with simplicity and elegance. You
can even automatically print multiple copies.

Although all versions feature tape save and load, the disk version
provides the Mini Disk Operating System common to the whole
Library, plus disk file linking for continous printing.

Professional features of particular note:

NEATH THE PICTURE ARE THE WORDS
'USE ME TO OPEN DOORS.' "
5090 PRINT:GOTO 1100

As you can see from the above example, each object
that can be LOOKed at is listed, followed by what the
player sees when he looks at the object.

MAKING THE RIGHT MOVE

In some Adventures, it is necessary to move certain
objects to find other objects (such as moving a bed to
reveal a trapdoor). We can keep track of these objects by
assigning a variable to them. If that variable is O, as it is
whenever the game is RUN, the object has not been
moved. When the player MOVES the object, the object
below it is revealed. Such is the case in the sample
"Mini venture" we have been making as we go along. In it,
the player must MOVE the altar in order to find a hidden
door. Here is a sample MOVE routine.

6000 'MOVE ROUTINE

6010 IF B$="ALTAR" AND L=5 THEN PRINT
"THE ALTAR MOVES. REVEALING A HID-
DEN DOOR.":LOS( 10)="DOOR":OS( 10)= "*"
:0(10)=5:ALTAR=I:GOTO 1100

If the player typed "MOVE ALTAR," and he was in
the same room as the altar (room 5), the program would
PRINT that a previously hidden door was revealed. It
would then add the door at the end of the object list (in
this case as object 10), identifying it as an immovable
object, and placing it in room 5. Next it would change the
value of ALTAR from to I — indicating that the altar
has been moved. From there, it zooms back to line 1 100
to ask what the player wants to do. Note that in the verb
list, if the player types PUSH or PULL the computer will
go to the same routine.

UNLOCKING SECRETS

The Adventurer has discovered a door. The door may
be in one of three states: open and unlocked, closed
and unlocked, or closed and locked. For the Adventure,
we will represent these possibilities by numbers: for
closed and locked, 1 for closed and unlocked, and 2 for
open and unlocked. DOOR will be the variable used for
this purpose. If you have more than one door, you could
call them DI, D2, etc.

When the player comes to the door, it is in its default
position — closed and locked (0). Thus before he can
open it, he must UNLOCK IT. Unlocking doors and the
like can be acheived very simply:

7000 'UNLOCK ROUTINE

7010 IF BS="DOOR" AND ALTAR=1 AND L=5
THEN INPUP'WITH WHAT";IS:IF I$=
"DISK" AND O(2)=l000 THEN PRINT "THE
DOOR UNLOCKS":DOOR=l:GOTO 1100

7030 IF B$="DOOR" THEN PRINT"YOU FIND
YOURSELF UNABLE TO UNLOCK THE
DOOR.":GOTO 1100

Line 7010 checks that the ALTAR has been moved,
and if you are in the room with the door (room 5). lfso.it
asks you "WITH WHAT?" If the player had looked at the
disk, he would have seen that it said "FOR UNLOCK-
ING DOORS." If he replies DISK to the question and
has the disk (object #2) then the door unlocks. (Unlock-
ing doors with disks may seem out of place to you, but
remember that this is an alien planet you crashed on.)

AN OPEN AND SHUT DOOR

Now that the player has successfully unlocked the
door he can OPEN it. In order for him to do that
though, he must: I ) be in the same room as the door, and
2) have first unlocked the door. The OPEN routine listed

Of course, it does no good just to have an open door
leading to nothing. So, let's modify our travel table so the
the door, which lies to the south, leads to the City of the
Ancients (room 7).

8020 IF DOOR=2THEN T(2,5)=7: T(l,7)=5

This modifies the travel so that a south passage from
room 5 leads to room 7 and a north passage from room 7
leads to room 5. The player has now successfully gotten
around the wall by taking another route.

AND THE WINNER IS...

Congratulate yourself. Your Adventure is 95 percent
complete (who said you couldn't write an Adven-
ture). The remaining five percent is printing a title page
and instructions (if necessary) and congratulating the
player when he solves the Adventure.

Usually, the Adventure is solved when the player
brings some key object or objects where they are sup-
posed to be. You can put a check in where the Adventure
prints the room description to sec if this is the case. In this
sample called Miniventure, the player must bring the oil
back to the room with the spaceship. The check to see if

UTORI AL/ ADVENTURE

Keys To Creating
Winning Adventures

By Bob Liddil

The Kid hunkers down over the wheel >f his '57 Chevy,
the floor shifter vibrating in his hand as he lightly
tickles the gas pedal. The massive 427 fuel-injected
engine purrs like a caged tiger begging for freedom. The Kid
impatiently steals a glance at the bib overalled moonshiners
as they lug the last jars of White Lightning for the run.

With the bang of the trunk lid closing, he's off! Small
stones and dust fly under his wheels as he whips the stubby
little car around the last dirt hairpin and onto the main
highway.

But Sheriff Bubba Clcmmons knows The Kid. He knows
there's "shine" in the back of the car and he knows that this is
going to be The Kid's last run. He has to stop him from
making it to Knawbone.

So begins the duel.

Does this sound like a teaser from a TV movie? Actually,
it's the premise for a BASIC language Adventure written for
the TRS-80 by a fellow named Don Boner with the help of
his daughter Freda.

Hold on, you say. Adventure is all caves and bats and
dragons and wizards. Not necessarily so. Not so at all.

Although the original Adventure, The Colossal Cave, was
all underground, the genre Adventure can be any subject
under thesun. Scott Adams, Grand Poohbah of Adventure,
released Adventureland. Pirate's Cove, Mystery Funhouse
and many other all time best sellers without once touching
on the "Dungeons and Dragons" thematics which dominate
today's current Color Computer market.

Strange Odyssey is an Adventure based on overcoming an
alien machine to accomplish the puzzle's solution. Sands of
Egypt is set in a remote desert which bears little resemblance
to the wizards'and warriors' worlds. Calixto Island employs
no aspects of Fantasy Role Playing. It is possible to create
brave Adventures under almost any theme at all.

Problems much more complicated than mere coding face
the would-be Adventure writer. He has to choose a subject
that will excite the player, make him desperate to find a
solution. It must be simple, yet complicated, frustrating but
satisfying and above all, it must be logical.

Here's what I believe constitutes the making of a good
Adventure.

SELECT A THEMEWORLD. Decide what timeframe

52 the RAINBOW February 1984

your program will exist in and stick with it. A Fantasy
World, for example, should be consistent throughout the
game. One would not expect to employ laser pistols in
combat against dragons. Traps should have the feeling of
the period. A pit of spikes or an acid bath such as found in
Tower of Fear is reasonable. A Cyclops, mythical or fantasy
figure, which vanishes after being killed, smacks of magic.
Since the tower was created by Blackheart Firethrower, ace
Necromancer, to hold his treasures, we find a level of believ-
ability about the program and the things we have to do to
win.

A modern themcworld such as that used in Thunder Road
employs props one might expect. The '57 Chevy, the lady
hitchhiker. Sheriff Bubba, always in pursuit, the dumb dep-
uty's roadblock, all combine to create an atmosphere of
authenticity that lends clues to the user about his next course
of action.

What themeworlds could you use for an Adventure?

FUTUREWORLD: How about an astronaut trapped in
a space lab that will soon fall from orbit? Officially, you
aren't allowed to try a rescue; they don't want to risk losing
you. But the trapped man is your friend and you must try to
save him. Props might include a space shuttle, a magnetic ID
card to activate the launch sequence, an angry guard who
would have to be sedated, an oxygen bottle, necessary to
save the "maroonee" from suffocation in the spacewalk back
to the shuttle.

EARTH PAST: As a gladiator in ancient Rome, you
must fight your way to freedom in the arena. You are pitted
against hungry lions and tigers for the edification of the
crowd and you win, ingeniously, by choosing the correct
weapon. But the mighty Nero has a last surprise in store for
you. It is a labyrinth, a maze of corridors containing
mechanical traps, enemy spearmen, deadly creatures, or
politicians making speeches, all designed to inflict cruel
death on you. But if you survive, all Rome will be at your
feet. Can you emerge victorious?

SPACE OPERA: The dead space ship with just a hint of
something amiss is a themeworld with many variables pos-
sible. In the classic text Adventure Death Dreadnaught,
what is amiss unfolds slowly as the player explores the ship.
Scenes of violence become increasingly evident in the form
of "screen prints" on the walls or in the power room where

"once splendid engines lay fused, mutilated and useless. "Of
course, escape becomes imperative once the presence of the
ferocious alien creature who did all this damage becomes
known. Props include food batteries, a laser pistol, oxygen
tank and more. There are so many different possibilities
within this formula that just outlining them would take
several pages. Obviously, every science fiction novel you
ever read holds clues to your space opera.

The Andrea Doria, a sunken ship scenario, an ancient
temple, a wild west resplendent with bandits and saloons, a
cemetery with graves that turn out to be the gateway to
Hades, a love boat, an island with a five-dimension stargate.
a time machine, a submarine, a mysterious planet with
robots guarding an ancient treasure — the divergence of
themeworlds is as universal as the imagination.

But, is it enough to have a good universe?

No.

PLOT LOGIC is the glue that holds all Adventures
together. Each piece of the puzzle must fit neatly into the
next. There must be a plausible solution for that brain teaser
which halts the program in its tracks. If there are flat tires in
The Kid's future in Thunder Road, then there had better be a
reasonable way to repair them or a spare and a CHANGE
TIRES command.

Adventure is an extremely Newtonian place. An author
should be prepared to provide a reaction to every input. If
there are too many "YOU CANT DO THAT" replies
appearing on the screen, you can bet that player will go back
to playing The King and not pick up your program again.

An object need not always advance the plot. A location
within the theme framework need not always place the
player closer to winning. But they should be interesting

diversions that enhance the overall believability of the game.

Tower of Fear has a room at the top of the ivy which has
exasperated Adventure players since the program's debut
three years ago. Once you get in, you simply cannot get out.
It is a classic cul de sac that diverts the user's attention from
his real task, that of getting into the tower. It takes awhile,
but after dying 30 times in one location trying to figure an
angle, one eventually goes back to the beginning and works
out the right sequence. By now. the player never wants to see
that stupid room again, not realizing that the author has
given it a secret door cued to an obscure action to be done
elsewhere in the tower.

The lesson here is to tie the objects and locations together
so that individually and collectively they form a cohesive
and decipherable puzzle.

PLAYABILITY: If you follow the rules of plot logic,
game will be very playable. But give your user more. Give
him lavish descriptions of his surroundings, being careful to
consider all the things he can GET or GO to. Be intricate
without being oblique, be tricky, if you're using pictures,
don't be unfair. Above all, even if you're using pictures,
don't be afraid to employ every application of language
possible. Have your player shaking his head in disbelief
when he discovers what you really meant when you dropped
him 30 yards straight down into a dragon's lair.

When you write an Adventure, you are in every sense,
creating a "compu-novel." a self-contained, well-plotted
story with twists and goals and puzzles and intrigue such as
to rival a book. Give your user a lean, playable, exciting
Adventure and he'll be back every time you write a new one.

Now. that wouldn't be too bad at all.

r.-

A Menu Is Helpful

For Choosing
The Right Course

By Don Inman
Rainbow Contributing Editor

If you are going to use a program more than once, proper
documentation should be provided so that the program
can be easily and efficiently used. The time spent on
documentation will result in time saved when the program is
used again. Documentation that is internal should include
lots of prompts as discussed in "Using Graphics," February
"83 Rainbow.

Menus used within a program serve a dual purpose. They
not only provide ease of program use, but they also aid the
programmer in writing a program that is structured by the
menu selections. Menus are probably the most neglected
item when programs are being written for our own use.

I'll use the graphics associated with a pie (or circle) graph
to demonstrate how menus can be used. In planning a
program and its main menu, you must consider how the data
will be entered, how the data will be manipulated, and how
the results may be used. Items on the menu should appear in
the order of use whenever possible. When a selection is made
from the menu, control is passed to the selected section of
the program. After the necessary chores are performed in
that section, a return to the main menu should be provided.
Subroutines appear to be an ideal way to perform various
sections selected from the main menu.

You know that specific information will be needed to
draw the graph. Therefore, the first menu item might be:

Pie Graph Menu

1) INPUT INFORMATION

This section will accept the information that you provide. It
will also calculate and set up the necessary parameters for
drawing the graph. It will then return you to the main menu.
Another section that might be desirable would be a preli-
minary drawing that uses the information provided in sec-
tion one. You might decide upon changes after looking at
the preliminary graph. We now have:

(Don Inman is the acknowledged master of micro-
computer graphics and the author of a large number of
books, including" TRS-80 Color Computer Graphics"
and "Assembly Language Graphics for the TRS-80
Color Computer" with Kurt Inman.)

PIE GRAPH MENU

1) INPUT INFORMATION

2) PRELIMINARY DRAWING

After viewing the preliminary drawing, a return would be
made to the main menu. If changes are needed to your
original information, you would select item 1 again to make
those changes.

After you have the graph drawn to your satisfaction, you
may have choices as to what to do with the results, such as:
send to screen, send to printer, save informaton on disk or
tape, etc. Therefore, we add a third section.

PIE GRAPH MENU

1) INPUT INFORMATION

2) PRELIMINARY DRAWING

3) OUTPUT RESULTS

Some of us cannot sit down and plan out a complete
program at one sitting. The temptation to sit down to our
Color Computer and begin is just too strong. If you feel this
way, you can stop at this point and decide how to program
the main menu. The options for the menu placement on the
screen are almost endless. PRINT@ statements can be used
to locate the text as desired. Remember, have 32 characters
per line and 16 lines with the print positions numbered as
follows:

February 1984 the RAINBOW 55

Now that the main program is finalized, we can move on
to the subroutines. We must decide what information is
needed to draw a circle graph. We know we can draw a circle
with the Color Computer statement:

CIRCLE(X,Y),R,C,E,B ,S
center ^^ radius color \ begin arc stop arc

location

height/weight
ratio

We also know we must provide the number (N) of sections
into which the circle is to be divided. We certainly need to
provide the X and Y values for the center of the circle and the
radius (R). A problem arises when we try to find a way to
divide the circle into sections. How do we locate the points

X(3),Y(3)

X(4),Y(4)

X(2),Y(2)

X(1),Y(1)

X(5),Y(5)

(X( l ),Y( l )); X(2),Y(2)); etc. to draw the lines separating the
secions? By looking at the circle diagram, you can see that
X(l) and Y(l) values can be determined by:

(X(l) = X(0)+Rand
(Y(l) = Y(0).

The other X(n),Y(n) values can be found by equations
developed in the April 1983 issue of the Rainbow in the
article "Regular Polygons." They were:

■X(2) = X(l)+COS(A)*R and

Y(2) = X( l )-SlN( A)*R, where A is the angle between the

lines drawn from the center of the circle to the
= points of the circle.

X(2),Y(2)

X(0),Y(0)

X(1),Y(1)

Therefore, we must provide an input that will describe the
angle for each of the section dividing lines. This can be done
as a percent (P) of the total circle.

PRINT"% FOR SECTION";Z;
INPUT P

P(2)=P(Z-I)+P - add new percent to old percent
A=P(Z)'3.l4l6/50 — calculate angle in radians
(total circle = 2 (pi) radians)

The complete information subroutine is:

1000 REM ** INPUT INFO **

1020 INPUT "NUMBER OF SECTIONS"!

After the information entries have been made in subrou-
tine 1000, control is returned to the main program where the
menu is displayed again.

The second choice, PRELIMINARY DRAWING, must
be written. Assuming you have already completed the first
choice, all the necessary information is stored in the compu-
ter. The second subroutine should provide a choice of
PMODE. SCREEN, and COLOR (if desired).

Lines 2030 and 2060 are optional. The loop at lines 2090-
2110 draw lines from the center of the circle to the calculated
points on the circle. Lines 2120 and 2130 hold the graph on

carefully and see if you wish to change the size or any other
parameter of your d rawing. Then press any key to return to

Alphanumeric Characters

We are always looking for additional methods to
help children use and learn about computers.
Although many children have reached the satura-
tion point in arcade games, many kids do not know what else
to do with their computers.

One of the features that probably attracted all of us origin-
ally lo the Color Computer was its graphic capabilities. This
has certainly been proven true through all of the many
arcade games that are now available. 1, however, am much
more interested in using the computer's features to enable
kids to draw their own pictures.

Drawing comes naturally to many kids. The C0C0 easily
offers all of the features necessary to capitalize on this
interest. A picture can easily be drawn and saved to tape or
disk. This picture can then be recalled at any time for view-
ing or improvements. The improved picture can then be
resaved. This is all easily handled through files.

This month's program merely scratches the surface of the
world of files. Files enable us to easily save information and
then reload or recall it for future use. In the December, 1983
issue of the Rainbow, Richard White wrote a lovely article
about understanding cassette and disk file operations. His
article is an excellent reference for those who wish to delve
deeper into the topic.

Our plan was to create an Etch-A-Sketch program and
then save the pictures that are created. Lines 1 10-310 create
the Etch-A-Sketch. The arrow keys are used for drawing.
They are the character strings numbered 8, 9, 10 and 94 on
lines 150-180.

A few extra features were included for interest. The "C"
key from line 190 allows the user to change and use all of the
eight available colors. The "E" from lines 200 and 330 act as
an eraser to improve the drawing possibilities. Pressing an
arrow and the "E" key draws a blank to enable moving the
cursor invisibly to a new location.

ROM locations 1024 to 1535 contain the information that
is pointed on a low resolution screen. Location 1024 is the
top left corner of your screen and 1535 is the bottom right
corner of the screen. There are 16 lines each with 32 loca-
tions for a total of 512 locations.

The picture can then be saved by PEEKing those loca-
tions. The computer will then know what is there. By POKE-
ing the same information back into those locations, the

ren, holds two master's degrees and has won awards
for the design of programs to aid the handicapped. He
and his wife, Cheryl, own Computer Island.)

computer can recreate the picture. This is how we will save
and then reload the picture.

Lines 350-400 will save the picture in progress when the
"S" key is pressed. A file called N$ will be opened on line
350. The "O" refers to output; the ft I refers to disk or
cassette; the N$ refers to the original name that we gave to
the picture on line 100. Lines 360-390 PEEK&W information
in the screen locations, save it in a file and then close the file.

Similarly, lines 420-480 will load from tape or disk and
print on the screen all of the information that was previously
saved under the particular N$ name. The "1" in line 430
refers to input. Lines 440-470 POKE back in on the screen
all of the parts of the picture, one location at a time.

This program can be run on cassette or disk systems. The
device #-1 refers to cassette whilea#l will refer to disk. This
version of the program was written for disk. Lines 350, 370,
390, 430, 450 and 480 tell the computer which device we are
using. Change the #1 s to #-ls on these lines if you are using
cassettes.

We have used the disk version of this program with sev-
eral classes of children. It was equally enjoyed by various
aged students. We give a new name (NS) to each new picture
that is created. Limit the name to eight letters or less. The
name is either the child's name or the type of picture that he
wants to draw. Using picture subject as the name can be
dangerous in a large group because when one child decides
to call a picture a certain name, then others will decide on
that name also. We had five pictures called "HOUSE" in one
class before we realized theerror. Each succeeding"HOUSE"
file will wipe out the previous one on disk. You will be able
to save at least 30 different pictures on a single disk.
Although you can easily save this many on a cassette, the
time involved in searching for each will certainly drive you
to tears.

Some children are timid about using any new computer
program. This program allows him to go back at a later time
and rework or improve any picture that was previously
started. Simply enter the name of any previous picture, use
the "L" key to load it and it may be reworked and resaved
time after time.

We have also used this program at home and in school as a
type of picture gallery or show. Pictures are loaded one after
another for evaluation or comment by the other kids. It's a
lot of fun and non-threatening because the pictures can so
easily be improved and resaved.

The Computer Island staff is always interested in your
comments. We would love to hear how you use the pro-
grams with your youngsters.

EDUCATION OVERVIEW

Microcomputers:

Isn't Always Better

By Michael Plog, Ph.D.
Rainbow Contributing Editor

A few weeks ago, I was invited to tour a large
mainframe computer complex. There were five
mainframes at the site, with over 300 disk (not
diskette) drive units. These are the large boxes that house
rigid disks about eighteen inches across. They are filled with
an inert gas. and the disk head rides a few thousandths of an
inch above the surface. Some of the newer disk units con-
tained a googolbyte of memory. A googol. by the way. is the
number one followed by one hundred zeros. That's more
data than the Color Computer can handle, but we are talk-
ing about mainframes.

Sidetrack — The mathematician Edward Kasner coined
the term for this extremely large number, when he asked his
nine-year-old nephew for an appropriate name. The boy
came up with "googol" and it was accepted. Sec. you can
learn something in an education column.

Well, back to the story. Another of the units was for mass
storage. This is a device that records information on tape,
much the same as my little computer. This tape, however, is
four inches wide and one hundred feet long. One such spool
of tape holds one hundred million bytes of storage. A robot
arm gets the correct spool from a honeycomb type wall,
loads the data into temporary disk space, and makes it
available to the user. No human hands need (or could)

(Michael Plug received his Ph.D. degree from the
University of Illinois. In addition to his work as an
educational researcher, he is a major partner in the
Center for Opinion Research, a firm conducting state-
wide polling in Illinois. The Color Computer is used in
all phases of the polling work.)

handle the mass storage tapes. Of course, there were the
regular computer tapes on hand - several thousand of the
large reels you see in the movies.

During the tour. I was shown several hundred modem
lines connecting the different mainframes to users all across
the city and state. They even had a fast printer there. 21.000
lines per minute. The biggest problem, understandably, with
the printer is keeping boxes of paper in it. It takes more time
to change the paper than to go through an entire box.

The total value of the equipment in this location is six
hundred million dollars. Naturally, security precautions
were extreme. The electric backup system alone was a com-
plicated process. Batteries could continue the work of the
computers for two hours, in case of a power failure. Then, a
kerosene generator can takeover. There is enough kerosene
in the tanks for two weeks.

I admit it. I was thoroughly impressed by all this power
and the sheer size of the computers. A friend of mine
arranged the tour, probably just to impress me. He is a
mainframe programmer, and can make the large machines
do just about anything except walk. He wanted to show me
what a "real" computer was like.

Well, I got home and had a little work to do on my Color
Computer. I had to finish a short program to calculate
something or other; prepare a word find game for students
in my wife's classroom: and write a letter to a relative. When
I sal down in front of my little machine, it did appear puny.
The printer seemed to take forever to get through one page.
Searching through my floppie diskettes somehow took
longer than normal.

Somewhere in the middle of my work, however, I devel-
oped a deeper appreciation for the microcomputer. There
was no sudden Hash of realization on my part; just that I
understand better the true value of a microcomputer com-
pared with a mainframe. And you know what — a great deal
of that value relates to public education in the United States!

the RAINBOW February 1984

Yes, dear reader, you knew all along I was going to get
around to education, didn't you. To be truthful, I did not
realize the experience of the mainframe tour related to edu-
cation. (Other than my own acquisition of information.)

The mainframe represents sheer power. Generally, that
translates to most of us as importance. I know that many
writers have spoken against the concept of "big is better," to
the point that the words are seldom used today. Yet. the
emotion is still present.

For educational purposes, too much power can be nega-
tive! The huge capabilities from a mainframe computer may
not be as helpful to students (and teachers, administrators,
etc.) as a smaller machine. There are several reasons for this,
only a few of which will be addressed here.

First is the difference between education and training.
Training can be seen as knowing why something works. It is
foolish to expect anyone other than a highly trained techni-
cian to know much about a mainframe computer. With the
microcomputer, however, even small children can learn
about them. Students in junior high school can learn more
about electronic theory than many adults will ever know
— simply becuasc of the motivation of the microcomputer.

Of course, the expense is a major problem. Most school
districts simply cannot afford a mainframe. Those that have
the capability to rent time on a mainframe often have higher
priorities for the money. Schools, however, can usually
locate enough funds for microcomputers.

Closely tied with the issue of money is the educational
value of "close-up" experience. When I was a graduate
student, I dealt with a mainframe computer. During all that
time, I never actually saw the computer. I passed typed cards
throughahalfdoortoa bored operator, who fed them into a
card reader. 1 received a printout from another bored opera-
tor. Most computer programmers today do not ever get
close to the computer. They work with terminals mostly.
Adults can handle this separation of relationship (in truth, a
cause and effect separated by distance and time). Children,
however, need a closer tie to understand the relationship
between their actions (keying something into a machine)
and the results (getting something out).

Microcomputers are more appropriate to students, just
because they are smaller, more manageable. Micros encour-
age a greater reliance on self; something all schools should
strive for.

It appears that educators have indeed received the mes-
sage that micros are important to schooling. As of January,
1983. over half (53 percent) of schools in the United States
had at least one microcomputer! The data on this subject is
naturally old, even by the time it is collected. By now, a
greater percentage of schools own microcomputers. This is
certainly a milestone. Just think, students in a majority of
schools in the country have access to a microcomputer.
There is a string attached, however.

M icros are not owned equally across schools. Elementary
schools in the south tend to be less computer-oriented than
elementary schools in the rest of the country. Poorer com-
munities tend to have elementary schools without micro-
computers. And non-public schools tend not to have micro-
computers. Now this is not surprising. Schools in poorer
communities tend to have less of everything — including
microcomputers.

Secondary schools in all areas of the country and social
strata tend to have microcomputers. True, poorer schools
tend to have less access for students to microcomputers than
do schools in more affluent areas, but the access is there.

In the not too distant future, the work force will be more
computer-oriented than now. Those students missing an
opportunity to learn about micros now will find themselves
at a disadvantage when they try to compete with students
from more enlightened school districts. We are putting a
greaterdisadvantage on those students who can least afford
an extra handicap.

The major uses of microcomputers in the schools is pre-
dictably programming instruction and "drill and practice."
I n almost all cases, above average students have more access
to microcomputers than do their peers with lower grades.

These findings arc provided by the Johns Hopkins Uni-
versity, Center for Social Organization of Schools. The
Center conducted a national survey of school uses of micro-
computers. If you are interested in the entire report, you
might try writing the Center at 3505 N. Charles St., Balti-
more, MD 21218. I cannot guarantee they will respond.

The Color Computer is not the bellweather machine in
schools. (You knew that already.) Those of us who have seen
the truth in equipment are not totally out of the picture.
More and more educational software is being prepared for
the Color Computer. By next month ( March. 1984 the Min-
nesota Educational Computing Consortium ( M ECC) should
have twenty programs available for the Co\or Computer.
This group is one of the largest not-for-profit producers of
microcomputer software. To get more information, you can
write MECC at 3490 Lexington Avenue North, St. Paul,
Minnesota 55112. or call at 612/638-0600. 1 can almost
guarantee they will respond. Even if you cannot use most of
the MECC software on your Color Computer, you might
still be able to use some of the MECC printed material aobut
microcomputers.

Talk to you next month. Until then, remember that the
best way to help education is to keep learning.

February 1984 the RAINBOW 63

You are the pilot of an ultramodern helicopter on a
mission to recover a precious artifact which, in
ancient times, was stolen from your land and hidden
in a series of treacherous caverns. As you maneuver your
copter through the caverns, you avoid deadly stalactites and
stalagmites, and dodge fearsome creatures that suddenly
materialize before your copter. As a last resort you fire your
powerful laser, clearinga path to safety. If you're skillful you
may even collect chunks of gold that line the caverns. At last
you reach the cavern of the artifact — the ultimate
challenge!

(Jason Nannen, a junior at Wethersfield [ Conn.] High
School, enjoys programming both games and practi-
cal programs for the CoCo. He is interested in I he field
of psychology and its application to artificial intel-
ligence.)

Yep, that's you when you play Cavern Copter, an arcade-
type game for the CoCo. Detailed instructions are included
in the program listing, but if you don't want an instructions
option, exclude lines 106-395.

Cavern Copter can be a fairly diverse game. The five
variables in lines 14-18 determine the difficulty of different
parts of the game. They are explained in the listing and may
be changed to modify the game to your own level of skill.
Experiment!

For neat visual effects, there are three unique routines: a
cavern-generator, a spiral explosion when the copter crashes,
and instructions that scroll across the screen from right to
left. If you include instructions, be sure to leave a space
before the last quotation mark in each line of data, as in the
listing. Otherwise, unwanted characters will trail when the
instructions cross the screen.

Hop in your copter and hit the caverns!

EDUCATIONAL SOFTWARE ■
LICENSE PLAN

for
public and private schools?

Max Jerman

The complete set of quality instructional software that was formerly avail-
able only at retail prices is now available to schools at less than 5% of its current
retail price.

This award-winning software is either now or soon will be running on Apple,
Atari, Commodore 64, IBM-PC, TRS-80, and TRS-80 Color Computers.

Over 250 disks containing more than 1200 lessons for grades K-9 in reading,
spelling, language arts, math, problem solving, math games, reading games, and
programs for young learners are included in the plan.

"HE PLAN— Schools join together to form a cost-saving consortium of 50 or
more members. One school or eductional agency acts as Host. The Host will
receive a master set of program disks and manuals. The consortium will be
licensed to make as many copies of the masters as member schools need for their
various computers.

THE BENEFI lS — Consortium schools will automatically receive updates
and new program releases at no increase in membership fee. There will be no
shortage of quality software for the most popular computers.

"HE COST — Only $250 per school per year. There is an additional start-up
cost of $250 per school to cover initial expenses. Licenses for specific computers
are available to large consortia or states at reduced cost.

AC I NOW — Form your own consor-
tium and contact us. Contact us directly for
the names of interested schools in your area.

Championship Golf
For The Color Computer

I'd much rather be out on
the links playing golf, but up
here in the north it's just too cold
after the first of November. (You also
tend to lose a lot of golf balls in the snow.)
Usually during the winter, 1 just watch golf on
TV and dream about hitting the little while ball.
However, this year is different because I'm playing
golf on my Color Computer.

Color Computer Championship Golf is a 16K
Extended Color BASIC program that combines graph-
ics, strategy, and a little bit of luck to make a chal-
lenging golf simulation. The program allows for up to
four players. In order to properly set up the scorecard, each
player's name must be kept to five letters or less. Once the
player's names have been entered, the scorecard is displayed
and the game begins.

Each hole is graphically displayed, and a blinking diamond
identifies the ball position. On the graphic screen, the green area is
the fairway, orange areas are sand traps, blue areas are water
hazards, the white area al the end of the fairway is green, and all other
white area is rough. The orange dot on the green is the cup, and the
yardage of the hole is displayed on the screen.

Any time you are in the graphics mode you will stay there until you
press the "X" key. Pressing the "X" key puts you in the text mode where
you will select your club and direction of shot. The club selection screen
allows you to choose a club on the basis of how far you want to hit the ball.

68 the RAINBOW February 1984

<■>

«.«* f!

\

CL

The number afler the club name is the average distance the
ball will go lor that club. Next you must choose the direction
you wish to hit the ball. Once you have done this, the
computer will display the distance you have hit the ball
based on a randomly selected percentage of the average
distance of the club you selected. It also displays how much
you hooked or sliced your shot based on a randomly selected
distance depending on you club selection. Finally, the com-
puter tells you where your ball has come to rest, for example
fairway or sand trap. Then it's back to the graphics screen to
display you new position in the hole, and you prepare for
your next shot.

Once you find the green the computer takes over. The
greens are divided into four"contours. "Contour I is closest
to the cup while contour 4 is farthest away. You have a better
chance of one putting in contour I . and a better chance of
three putting in contour 4. But you will usually two-putt in
any contour. The screen will not display your number of
putts and your score for the hole, and it will be the next
player's turn. Once all players have played a hole, an
updated scorecard will be displayed.

Due to memory limitations on a I6K machine, there are
only nine different graphic holes. These nine are repeated to
make an 18-hole course. Since the graphics are in PMODE
1 . 1 used the command PCLEAR2 to increase the available
memory to 1 1559 bytes. Before you begin to type in or load
the program, you must perform a PCLEAR2 to get enough
memory. Even then after running the program there will be
only a few hundred bytes of memory left.

It is not easy to break par with the program. It takes a
while to get used to estimating graphic screen yardage, but
as you do you will see your scores get better and better. But
even when you have mastered this, an errant shot can land
you in big trouble. There is quite a bit ol strategy involved to
position your shots to avoid water hazards and sand traps.
And it's up to you to decide whether to "play it safe" or to
"go for it." All in all, it may not beat playing the real thing,
but it sure beats watching others play on TV.

(Mike Knolhoffis a science teacher currently pursuing
a master 's degree which emphasizes computer applica-
tions in education. He has been programming for over
two years and has taught BASIC and LOGO to junior
high students. Mike 's other interests include photo-
graphy and. of course, golf.)

You are one of many priests of Ra who has accepted the challenge of the touchstone. The
challenge is a way for any of Ra's followers to become a favored high priest.

For the short time you will be in his temple, Ra will grant you limited use of his powers to
help you on your challenge. As you will find, a ray of light shoots from your eyes that kills
anything in your path. Also, Ra will give you a lamp filled with an elixor which when spilt,
causes your enemies to freeze.

At daybreak, as you enter the temple, you hear Ra's voice reminding you of what you know
so well: if you can get to the touchstone you will be highly favored. Further, he warns you that
your now working powers are only temporary, and that you must be successful in the mazes
to be granted more time. You enter, ready for anything. . . .

GENEALOGY

hen niN wile's fa ro-
ily decided 10 have
a familv reunion,
im wile assumed some of
the responsibilities forgath-
ering ihe clala to be used in
creatinga familv tree. As she
anil her eousins dug into the
project, meeting regularlv to
compile their lists of names.
weddings, and birth dates,
etc.. I couldn't retrain from
offering lO input the mount-
ing data into some sort of
reeord-keeping program I
would write for my Color
Computer! my wife is.ltalian
H lid has quite a large family).
As it turned out. I didn't
aeeomplish too mueh in
terms of easing family tree
researeh. Instead. I deeided

to eoneenirate on a novel

wav to present the results. In
im Futility Tree program.

all the required data is chronologically arranged and coded
Via pATA statements. Ihe program presents one logieal
I'll roil) "unit" at a lime, waits for some predetermined inter-
val, and then moves on to the next lateral 01 lower "familv
branch." It's designed to displav its way "down" any given
branch until the "tip" is reaehed and then revert to the next
lateral familv member's "limb" . , . that being the next
youngest child ol the top-ol-lhe-lrcc parents. What I aetu-
allv did was bring the computer anil monitor to the reunion
and let it run all day (it evcles around and reruns itself) where
it proved to be quite an attraction.

(Dick Seaherg, a systems development department
manager in a New England health insurance company,
resides in H'alling/brd. C'T. He and his 1 4-year-old son
have collaborated on several family-type \\\su. games
which arc being marketed hy Spectral Associates.)

Rich** 1 8C0M

I he version here, ol course,
contains a hv pot helical and.
I hope, fictitious tree of some
strange intermarriages. Since
a picture is indeed worth a
thousand words. I would sug-
gest that the data .statements
be typed in as shown before
attempting to plug in vour
own familv. Certainly, there
are idiosyncrasies inanv tree

a good sampling here. Once
you see how it works, you'll
be able to hard-code in any
special llashing-divorce signs,
clone-notations, reincarna-
tions or other circumstances
unique to vour own familv
heritage.
Starting at line 40 you'll

as a code number ol

liaeh code tells the program
how to treal and displav ihe data from the next read which.
fur .si 111 pi icily, follows within ilk- same DATA statement.
l - 'or the sake ol a I6K computer and ease ol explanation.' I'll
assume the relative position (pun intended) ol a grandchild
to put things into perspective. Also, we'll assume that I'll be
creating a tree commencing with mv fraternal grandparents.

Code I - Mv drandlathci (lull name)
Code 2 Mv ( iiandmoiher (lull name)
Code 3 I I'eir wedding year

Ihe above data will display liisi at screen center.

Code 4 I heir children (my lalhei plus any aunts un-
cles), first name, comma, war ol birth (in order bv vear of
birth)

the RAINBOW February 1984

There should be 1 1 Code 4 entries to force the grandparents'
data to scroll to the top of the screen where they will remain
throughout. Use additional blank statements (DATA 4„) if
needed. If more than 1 1 children were born, you'll have to
repeat Codes I and 2 entries followed by the additional Code
4s. (See lines 90-180)

(Codes 5 and 6 exist only if a "4" married)

Code 5 = Full name of my parent, aunt or uncle

Code 6 = Full name of spouse of (5) above

Code 3 = (as previously described)

Code 4 = Their children (as previously described). This

will be my family unit (myself, brothers/ sisters)

or aunt/ uncle unit (cousins)

There is a maximum of six Code entries but no minimum. II
more than six children were born, you'll have to repeat
Codes 5 and 6 followed by the additional Code 4s.

Marriages and children of next genera lions (mine and on)
are coded next similarly to last generation but with the
following exception: Code 8 is used in place of Code 3. Its
format is as shown in line number 350 and is used only after
the first marriage of the generation. Its purpose is to display
the prior generation's parent names just under the grand-
parents while the displays continue to the "tip" of the
branch. Code 8 has another format (line 550) to blank out
the prior generation's parent names. Code 9 is the last
DA TA statement and should be coded as shown.

Lines 1710-1790 are optional in that the "flag" they draw
is of no known origin, but it allows for a logical place to
insert your own emblem or title to dress up the running
display. Line 1800 contains a waiting interval which is used
between displays to allow enough time to view each screen.
During preparation, you will want to shorten it to 300 or
less. Kev in the program as shown and save it to tape using
CSAVE FAMTREE.

All of us have, at one time or another, probably consi-
dered gathering together certain family data such as that
which this program needs in order to function. Here's your
chance to follow through and have fun doing it.

'REAL TALKER

HARDWARE Voice Synthesizer

COLORWARE..
only... $59.95

THINKING OF BUYING A
COCO VOICE SYNTHESIZER?

READ THIS....

Making your computer talk couldn't be any easier!
•Real Talker' is a full featured, ready to use, HARDWARE
voice synthesizer system in a cartridge pak. It uses the
Votrax SC-01 phoneme synthesizer chip to produce a
clear, crisp voice.

FREE TEXT-TO-SPEECH

Included free with 'Real Talker' is Colorware's
remarkable Text-to-Speech program. This is a truly
powerful machine language utility. What it does is
automatically convert plain English to speech. And it has
an unlimited vocabulary! For example, use it in the direct
mode: Type in a sentence or a paragraph, even mix in
numbers, dollar signs, etc., then press enter. The text is
spoken. At the same time a phoneme string is generated
which can be saved to cassette or disk, modified or used
in a Basic program.

We originally planned to sell this major piece of
programming for about $40.00 but decided it was so
useful that no 'Real Talker' user sholild be without it.
Besides, it really shows off the capability of 'Real Talker'.

Also included with 'Real Talker' is our unique Phoneme
Editor program. It allows you to explore and create
artificial speech at the phoneme level. Phenomes are the
fundimental sounds or building blocks of word
pronunciation. There are 64 different phenomes, as well
as 4 inflection levels at your disposal. Creating and
modifying speech at the phenome level is both fascinating
and educational. The Phenome Editor may also be used to
customize the pronunciation of speech produced by the
Text-to-Speech program.

You don't have to use any of our utility programs
though. If you write your own Basic Programs, you will
find the pocket sized Votrax Dictionary (included free) is
all you need to make your own Basic programs talk. This
dictionary gives you quick access to the phenome
sequences used to create approximately 1 400 of the most
used words in the English language.

How about compatibility? 'Real Talker' is compatible
with any 16K, 32K, 64K, Extended or non-extended Color
Computer. It works with any cassette or disk based
system, with or without the Radio Shack Multi-slot
expander. No other synthesizer under $100 can make this
claim. Most other CoCo voice synthesizers require an
expensive Multi-slot expander in order to work with the
disk system. 'Real Talker' requires only an inexpensive Y-
adapter. This is an important consideration if you plan on
adding a disk or have one already.

'Real Talker' comes completely assembled, tested and
ready to use. It is powered by the CoCo and talks through
your T.V. speaker so there is nothing else to add. Price
includes Text-to-Speech and other programs on cassette
(may be transferred to disk), User Manual and Votrax
Dictionary. ONLY $59.95

'Y-BRANCHINC CABLE' For disk systems. This 40-pin, 3
connector cable allows 'Real Talker' to be used with any
disk system $29.95

YOU DECIDE....

Order yours today on our Toll-Free Order Line. If you are
not delighted with your 'Real Talker' system, simply
return it within 30 days for a prompt, courteous refund.

WHICH "WEIGH" TO GO?

Taken from Mieroware's brochure, "OS-9 is a Unix-like
multitasking, real-time operating system. Its modular
structure makes OS-9 easily adaptable. OS-9 is widely
used for applications in data processing, industrial
automation, communication, instrumentation and
education."

OS-9 FEATURES:

• Real-time multitasking executive.

• Hierarchial disk-file directories.

• Device independent, interrupt-driven I/O

• Modular software memory management

• Command interpreter with I/O redirection

Developed by Microware and Motorola about 3 years
ago, OS9 has enjoyed a loyal following among users.
There are several very good languages available for it.
These include Basic09, Pascal, "C" and Cobol. Also,
there are 2 exceptional Word Processors; DynaStar and
Stylograph. To check spelling, Dynaspell and
Stylograph's spelling checker are available. OS-9 is an
excellent choice for control applications, and because
of the demand for UNIX like operating systems it is an
excellent choice for the CoCo. On the CoCo it offers
type-ahead and a limited multi-user capability. Disk
support is single-sided, double-density up to 40 tracks.
Printer baud rates up to 4800 are supported. The
operating system also provides graphics capability
although the text screen, like that under RS DOS, is
only 32 by 16. Memory is 42K of user RAM (33K with
the use of a HiRes screen).

FHL has more software for OS-9 than everyone else
combined! The perfect first choice is 'O-Pak', which
adds a Hi-Resolution Screen and Copy utilities. Many
other software packages require O-Pak to function.
Some of the other OS9 software packages available
from FHL are: SUPER SLEUTH Disassembler, CRASMB
Cross Assembler, DYNAMITE-t Disassembler, A/BASIC
Basic Compiler, and DO - A Job Control Language.

catalog. It's FREE!

FHL FLEX is the most popular "true" operating system
for the CoCo. It has been available for 2 years and
has more software available for it than any other Color
Computer operating system. FLEX is easy to use and
is known as being 'User Friendly. 1 The abundance of
excellent software available makes it a good choice for
the CoCo. FLEX has 46K of user RAM WITH a HiRes
screen. This makes it possible to run complex business
software like A/R, and spreadsheets like DynaCalc.
FLEX supports 35, 40, or 80 track single or double-
sided 5 1/4" drives. It even supports 3" drives! With
FLEX you get:

* One disk startup w/ 1.0 or 1.1 ROM

* Easy startup, just type RUN "FLEX or DOS

* HiRes screen built in

* Online HELP capability

* Supports all 3" or 5 1/4 " drives:

* Option: DBAS1C (RS Disk Basic under FLEX)

* Great programming ease

* A User Friendly environment

* A system suited to the casual user

* The most support software for any CC DOS

* Hundreds of articles to help the new user

All this for only $69.95
Optionul DBASIC $30.00 extra.

FINAL NOTE

Making the choice between two very good operating
systems is undoubtably difficult. No other small
computer has such a rich choice. The Color Computer
user is extremely lucky to be able to choose from such
offerings. So, the choice is hard. You could buy both
and then decide, but that is costly. Many of the CoCo
publications have been writing articles and columns
about FLEX for 2 years, and similarly many will be
writing about OS-9 too. It may take a while before a
comparison can be made from them. The best way to
decide for now is to determine what your software
needs are and buy the operating system that supports
them. We at FHL support BOTH operating systems. Call
us for help concerning software availabUity or any
other assistance you may require. Send for our FREE
32 page catalog and see our other ads.

ere's the latest printer mystery for those who have
the Printer Artist program from the November
issue of the Rainbow. Of course, we won't tell you
•i'r what it is. other than to say that it's an appropriate February
•$* epistle for your girlfriend, boyfriend, wife or husband.
y. Since the first Printer Art first appeared in Rainbow,
:i!V we've heard from a couple of people with problems. In one
ease, a reader had trouble with the Halloween witch. We
couldn't duplicate the problem ourselves, but alter an
exchange ol correspondence we found out that his CoCo
was actually adding wrong. Has anybody else had this
experience?

Also, some folks with non Radio-Shack printers (like my
Gemini 10). and some with the new DMP-120. occasionally
find that the printer drops the first character in a line. One
reader said Radio Shack told him the trouble was with the
computer's output. Anyway, you can solve this problem by
adding a half-second line delay, .lust POKE 151. 1 28: POKE
152,0 before RUNning the program.

To create the drawing below, run the Printer Artist pro-
gram and type in the characters as you see them listed here,
one line at a time. For example, if a line reads "23sp I6M
1 4: "you should strike the space bar 23 times, strike the"M" ( *«

THE
AMAZING ADVENTURES

OF

Conquest of the
Castle Caverns

By Gregory Clark

Karrak is a warrior in the kingdom of Blenfor. His
strength and courage have reached almost legend-
ary proportion, in spite of his relatively young age
of 26 cycles.

He has heard of strange things going on in the area of an
old castle located in the Eastern Mountains. So old is this
castle that the original owner's name has been forgotten. All
that is known for sure is that no one has lived there since his
death.

Recently people, livestock and materials have been
reported missing in that area. The reports have been coming
at an ever-increasing rate. Along with the reports are
rumors to the effect that an evil entity has taken up resi-
dence in the old castle and has been sending forth terrible
creatures into the countryside to pillage.

Karrak arrives at the entrance of the old castle. Vines and
brambles have all but overgrown the walls. There is no sign
of recent passing in the dirt leading to the entrance. Karrak
takes note that, as he steps forward and enters, the sun
disappears behind an especially dark cloud.

February 1984 Ihe RAINBOW

BLACKJACK PRO

SKILLWARE

INSTRUCTIONS

Karrak is a four-part Adventure game
written for the 16K Color Computer in
non-Extended BASIC.

There are six listings for the game. To
assemble them into four Adventures,
follow these steps:

Type in listing 1 (KAR-1).

*lf you have Extended BASIC, now
substitute listing 6 (KAR-6) for lines
200-240 in listing 1. This is a faster
search routine and will speed up the
playing considerably.

Make four copies of listing 1 on four
different tapes. These will comprise the
base of the four Adventures. Make sure
of your typing at this point, as a mistake
here will appear in all four Adventures
and will cause you to have to bug out
four programs instead of one.

With listing I in memory, type in list-
ing 2 (KAR-2). Save the result on tape
and label as Game I.

Turn off your CoCo and then load
your next copy of listing I into memory.
Now enter listing 3 (KAR-3). Save the
result on tape and label as Game 2.

Turn off your CoCo and then load
your next copy of listing I into memory.
Now enter listing 4 (KAR-4). Save the
result on tape and label as Game 3.

Turn off your CoCo and then load
your last copy of listing 1 into memory.
Now enter listing 5 (KAR-5). Save the
result on tape and label as Game 4.

You now have four separate I6K
Adventures, but — before you load in
Game 4 and attempt to solve it in record
time — read on. Karrak's four Adven-
tures must be played in order. Each time
a section is completed, the program will
instruct you in making a data tape. This
tape must be entered when you start
Games 2-4. This allows for two things
while it is not a "game in progress" save,
it allows you to finish one section and
not have to keep playing. You can come
back at anytime and pick up where you
left off, at least by game. It prevents
someone from starting on Game 4 and
cheating him/ herself out of the first
three games.

Karrak is written for the beginning
Adventurer; the first two games are
meant to be an instructional experience.
Parts three and four get down to some
real Adventuring. Asa word of caution,
don't hurry through each section; Adven-
turing is not a race. In fact, you can get
from one section to another without
getting everything you may need in a
later game.

Karrak is an interactive Adventure.
What I mean is, if you just move about
from room to room and don't do any-
thing, all you will get is death. You have
to imagine you are Karrak. Look at
things, take them if you feel they may
help you later, try different actions. This
program has a built-in vocabulary of
actions and objects. It would be unreal-
istic for me to believe that you will not
notice them as you type in the listings.
Don't be ashamed to write them on a
piece of paper for future reference, you
should have fun with this program —
not heartburn. The whole premise of an
Adventure is to put the actions and
objects together at the right time, in the
right order and solve the puzzle.

When you load in Game 1 you will see
a title page and then a screen of infor-
mation. You will be asked what you
wish to do. Remember, you are Karrak,
not the person who just typed in the
listings. All you have to work with now
is what you have on the screen. You may
now attempt to do anything you wish,
within the confines of the program's
vocabulary. You may, for example,
drop your sword by typing in "drop
sword" and pressing [ENTER]. You
will then be shown what the result of
this action is. In this case, you will be
advised that there is a sword now on the
ground. (Hint — don't leave it there.)
You may use any combination of actions
and objects you desire. Not all will work
as most will not make any sense until the
correct time. Along with allowing you
to input actions and obects, there are a
few one-key entries allowed. These do
away with repetitive typing. For exam-
ple, you just input "E" to move East,
rather than typing "Move East." A list-
ing of these follows:

The first letter of the direction to
move is all that need be entered.

& Restores the screen if the [CLEAR]
or [BREAK] key are accidentally
pressed.

[ Gives the room description, if any.
I Gives a list of items in your hands.
— Gives a list of items in the sack.
] Gives Karrak's strength ( more about
this later).

! Is used in combat. It is equal to "hit
the opponent with major weapon."
= Is used in combat. It is equal to
"hit the opponent with minor weapon"
Now, some answers to those ques-
tions. If Karrak's strength reaches zero,
he is dead and the game ends — you
have to start over and try again. A
major weapon is a sword or mace, a
minor weapon is a dagger or a hand axe.
In combat, if you have two major wea-

92

the RAINBOW February 1984

pons in hand, the sword is the weapon
used. In other words, have only one of
each type when fighting, or you will not
gain anything. If you find you are con-
fronted by an enemy, just enter "!" or
"="and the results of. the action will be
displayed. Choice of weapons may be
crucial. As an example, in real life, if
you faced a fire, a handful of tissues may
be fine for a runny nose, but I'd rather
use the extinguisher. You have to choose
based on the opponent. This may mean
a few deaths, but all you have to do is
rerun the program to get another chance.

One more word of ad vice — this is an
Adventure, based on a make-believe
character in an imaginary setting —
don't be surprised if a few touches of
magic are thrown at you.

Karrak is ready to step into the castle;
imagine yourself as a mighty warrior
and step in with him.

PRICKLY- PEAR SOFTWARE

QUALITY PROGRAMS FOR YOUR COCO & TDP-100

PROGRAMS REQUIRE 16K EXTENDED BASIC FOR TAPE, AND 32K DISK UNLESS OTHERWISE NOTED.

FOUR GREAT NEW PROGRAMS

Varalyzer

A breakthrough in programming utilitiesfrom theauthorof
Colorkit! You may need a little background for this pro-
gram. The first time you mention a variable in a BASIC
program, the computer assigns a space in the variable
table in memory. It starts at the bottom of the table and
works up to the top. and the next time that variable is called
in your program the computer goes to the variable table to
look it up. The search starts at the bottom of the table and
continues until the variable is located. This takes time, and
the farther up the table the variable is located, the longer it
takes. There is a BIG SPEED ADVANTAGE in having the
most frequently called variable located first in the table,
with the next most frequently called variable second, etc.
This program simply examines your BASIC program while
it is running and then actually modifies it to speed it up!
Speed increase will be from 5% to 75%, depending upon
the program, and we include a list of other tips to speed up
execution even more. This program will also print a list of
the variables used in the program and tell you how many
times each is called. VARALYZER is 100% machine
language and REQUIRES 64K to run. Works fine on either
disk or tape systems. S24.95

Clone Master

This is the ultimate disk backup utility, and who else but
Prickly-Pear, originators of Omni-Clone, could bring it to
you. If you are tired of waiting for your BACKUP command
to finish, you'll like the speed of CLONE MASTER. This
program checks the computer memory size, and if you
have a 64K machine it will do a backup on a full disk in
about 7 minutes — including formatting the destination
disk— with only THREE swaps, not the seven you are used
to, and if you are running multiple drives, CLONE MASTER
will handle up to 4 double-sided drives. In addition, al-
though we can't guarantee that CLONE MASTER will back
up any disk, it can handle backups of any non-standard
(protected) disk we have seen — not only on the Color
Computer, but on Model III and IV, IBM PC, Kaypro,
Osborne, and Atari, It handles up to 256 tracks, single and
double density— even on the same track. CRC errors, and
lots more. Itevenchecksthespeedofyourdrivesforyou! If
you are using a disk drive, you know how disks will crash,
so don't leave your valuable software unprotected any
longer. Back it up or lose it! CLONE MASTER will adjust to
any memory size and works with any version of the ROM's
— including the JVC controller. S39.95

$1.50 shipping for each program ordered. (Shipping free

ERLAND

The most complex
simulation we have)
ever seen, and C
you VIKING! fans
will want to take
note. This game
has you running
a small holding

in old Ireland. You must manage your land,
sheep, army, markets, fishing fleets, taxes, and""
many other factors while you try to rise in rank to become
King or Queen. You may attack — or be attacked — by the
other players, and you will have to face the fact that there
isn't enough land to go around, and you may have to take
some away from someone else! This 32 K game is con-
siderably more complex and difficult than our super
popular VIKING! Because of this, we have added a save-
the-game feature, ERLAND is for 2 to 5 game lovers, and
will warm the heart of anyone who liked VIKING!, Monopoly,
or other classic strategy games. This game Is a hybrid of
Extended Basic and Machine language. The disk and tape
versions are not interchangable. Tape — $24.95; Disk —
$29.95

Satellite

Tracker

Satellite Tracker ^

If you are interested in reception of transmissions from the
television satellites, you will need this program. It does all
calculations associated with planning and setting up a
satellite dish antenna. It figures antenna gain, signal to
noise, aiming point for any geosyncronous satellite, effect
of various quality amplifiers, and a lot more. The program
will tell you whether a dish is practical in your location, how
big it needs to be, and what kind of picture quality and
signal strength you will achieve. If you are thinking of
investing in a system, don't make a move until the results
are In. Requires 32K extended BASIC and some (limited)
knowledge of satellite terms and language. $79.95

A Dictionary Program is Useless

Unless It's Perfect.
That's Why We Are Introducing

SPELL 'N FIX II

A Spelling Dictionary Program is supposed to help you catch and fix mistakes in word processing text. It should
be simple and convenient to use. It should be fast. And above all, it must be accurate.

SPELL 'N FIX is all of these. But now
SPELL *N FIX II is even better! Look at the
comparison chart to see why.

SPELL *N FIX II finds and fixes spelling and
typing errors in a single pass. As SPELL 'N
FIX II proofreads your text, you see it all (in
full upper and lower case) right on the screen.
When a suspect word is found, you see it in
context as part of the text. You can
immediately search the SPELL 'N FIX II
dictionary for the correct spelling, and put the
right word into your text in a flash.

Most important of all, we take great pains
to make sure that SPELL 'N FIX is accurate
and complete. SPELL *N FIX II comes with a
20,000+ word standard dictionary which
contains many more words than the average
person uses. By allowing you to add your own
words, SPELL 'N FIX II gives you the
advantage of a short, fast dictionary that can
contain all the words you use (including your
name and address, special words from your
business, and even foreign or coined words.)
We don't stuff our dictionary with useless
words (some with foreign spellings or
downright wrong like absorbancy, accident-
ly, accts, agcy, aix, or analyse as you find in
other programs' 60,000 word dictionaries.)

Regardless of which you choose — the original SPELL 'N FIX (available on tape or disk, for 16K or larger
computers, now at a new low price with generous upgrade terms), or the new SPELL 'N FIX II — you will
understand why we say

STAR — KIBBITS

It seems like just yesterday that I wrote the first Star

— Kibbits column (though it wasn't called that then —
I called it "A Word From the Sponsor"). But here it is

— a whole year later. Time does fly!

?IO ERROR

Familiar message on your disk system? Perhaps the
problem is noise. Let me explain.

A few weeks ago, I was asked by a local
businessman to check out one of his four CoCos. I
went to his office, and found that one of his Radio
Shack drives was making a lot of errors.

We disconnected the drive and went to a local
Radio Shack service center. Imagine my surprise (and
embarrassment) when the drive worked perfectly on
their test bench. Back to the office and more IO
errors.

After some headscratching (not much hair to get in
the way), I decided that Radio Shack drives must be
very sensitive to external magnetic fields, and that this
drive was picking up noise from the motor of a blower
he had installed to keep his CoCo cool. We placed the
drive to the right of the computer, on a small dish rack
from the local 5-and-10, and his problems went away.

When you think about it, the read-write head in a
disk drive works on very low level magnetic fields, and
can easily pick up noise from nearby electric motors
or transformers. The MPI drives I am using on my own
system have a small copper shield near the head; the
drives don't work very well at all if you accidentally
leave it out. Some drive manufacturers even tell you
not to mount two drives next to each other, since they
will pick up noise from each other's motors.

Though this particular drive seemed more sensitive
than most, still it's not surprising that where you put
ihe drive can make a big difference. If you are having
problems with IO errors, try moving the drive far away
from everything else. It might help.

DOUBLE — SIDED DISKS

We are selling a complete disk system with a disk
controller, a double-sided 40-track drive, cabinet,
power supply and all cables, all for $400. The
advantage, of course, is that the double-sided drive
gives you the capacity of two regular drives for just
slightly more than only one.

If you currently have a double-sided drive, send us a
large self-addressed stamped envelope and we will
send you free details on how to use it with your CoCo.

That's it tor this month — see you next time.

This, quite
literally, is the
color computer
America has been waiting for.
One of the best sellers in the
United Kingdom, the Dragon wi
soon be manufactured by TANO
\o serve American consumers
who want a serious, affordable-
computer; one that has
proven itself at providing
educational and home
management applications as
well as fun and games. To
meet this challenge, the
Dragon was born. With a
standard 64K of RAM. A
professional typewriter-style
keyboard guaranteed for
20 million key operations.
And an impressive array
of options which include
disk controller and
drive, a printer, audio
cassette recorder, a
modem (RS-232 seria
I/O), joysticks, game
cartridges and a free
BASIC training manual.

Using the new 6809E Microprocessor (a great advance on
the original 6502 still used by our competition), the Dragon
brings advanced computer functions well within your
reach. And priced below $400, it's anything but expensive.

But these aren't the only points of difference with which
our Dragon roars. Unlike most units, the Dragon gives
Extended Microsoft"" Color BASIC as its standard
language while the competition is still stuck in Microsoft'"
BASIC training. The Dragon's advanced graphics features
include set, line, draw, circle, paint, print ui and print
using. Of course the Dragon also features advanced
sound capabilities.
'Microsoft'" is a registered trademark of Microsoft Corp.

THE COLOR
COMPUTER
YOU'VE BEEN
WAITING FOR*

And full editing
features allow you
to insert, delete
or change at will.
Oh yes — don't forget
the colors! The Dragon features
nine; with five different resolutions
from 512 points of text (16x32)
to 49,152 points (256x192)
at high resolution. And you
can view these amazing
phenomena through
either your composite video
color monitor or VHF TV.
So goes the Dragon's
story. If you'd like to
know more, just mail the
coupon or call George
Merchant (our Director
of Marketing) toll free
at 1-800-327-7671 .
Software developers
and dealer inquiries
are welcome. The
Dragon is destined
to become legend
as America dis-
covers its great
performance is
no myth.

Please send me more information on the Dragon.

MINER BY LARRY LANDWEHR

Like his father before him, Sid is a coal
miner. Working hundreds of feet below
ground it is Sid's job to blast the rock
so that the coal seam is exposed. See if
you can direct Sid to the most productive
areas. How many lumps of coal can you
collect before you run out of dynamite?
Young and old alike will enjoy this hi-res
all machine language game from the author
of "IN ASSEMBLY LANGUAGE".

EXECCART 3Y PETER KARWOWSKI

EXECCART is a M/L program that allows you
to copy ROMPAC programs to tape. They can
then be loaded back into a 64K CoCo and
examined or modified. You can run most of
your ROMPAC 's from disk without ever
having to remove the disk controller. This
saves tremendous wear and tear on the
contacts. EXECCART may also be used to add
a loader to your own programs to turn on
64K and to copy your BASIC ROMs into RAM
so that you can make modifications.

THE SPOOLER BY PETER KARWOWSKI

Whenever you use your printer, your
computer is totally dedicated to feeding
it. This isn't such a problem when you
just want to print out a couple of lines,
but LLISTing a long program can be very
boring. If you have better things to do
than sit around waiting for the printer,
then "THE SPOOLER" is just what you need.
THE SPOOLER will work on ANY TRS-80 Color
Computer from a 16K right up to 64K with
disks. Extended BASIC is NOT required.

SWISS ARMY KNIFE BY RALPH BLOCH

One of our most prolific authors (PRETTY
PRINTER-P.U.F.F. -LIBRARY) has come up with
another winner. As the namesake of this
program has many blades so SAK has many
functions. The disk owner will find it
indispensable for diagnosing and fixing
the many gremlins that attack a disk
system. It will work on any number of
tracks and can even read FLEX disks. By
copying one sector at a time you can often
save an otherwise uncopyable disk.

A IVtntet

It's that time of year again when you can bun-
dle up and go out in the crisp winter air to
make a snowman or sit by the cozy fire and
dream about someone else making that snowman
- like your CoCo.

Here's a short I6K. ECB program sent to us by
Andrew L. Shemo of Canton, Ohio that makes
your winter wonderland come true. Winter is a
Hi-Res graphic presentation of a chilly, familiar
scene with falling snow, trees and a snowman. II
your computer will not accept the high-speed
poke (POKE 65495, 0). delete lines 460 and 510.

So, build a fire, make some cocoa and let your
CoCo draw a winter wonderland.

COLOR BASIC COMPILER™

ii you have ever written a BASIC program only to find that it runs too
slow to provide any action and haven't had the courage to learn
assembler: then the Coloi Compiler'" is the answer It lets you write
your program in easy BASIC and then converts it into fast machine
language After you lun youi compiled program, you may find it
necessary to add some delays because the Color Compiler™ will make
youi program run an average of 40 times faster

The Color Compiler'" features a total of 46 commands and functions
Most of these are a subset of Extended Color BASIC The Color Com-
piler is limited to integer variables All floating point and string handling
can be done in a BASIC program which calls the compiled program
Passing information from BASIC to compiled programs is very easy The
Color Compiler™ generates position independent code so that you may
put the compiled program anywhere in memory, including into a ROM-
packl It requires 32K and a disk drive, leaving I6K of user work space

With Mac the limitations of having to put all source in memory, or
having all binary in memory are a thing of the past Mac can handle
any size source input file And with the LIBS command |included in
RSDOS and OS-9 versions), you could even assemble source from up to
foui drives into one output binary file. The Macro capabilities allow you
' reate standard subroutines only once, and then simply call them

ght Steps To Writing Solid

"ware Documentation

By Robert Tyson, Ph.D.

There are three reasons lor writing software documen-
tation: ( 1 ) so the user can use it, (2) so the user can
modify it to his needs and use it, and (3) so the author
can debug it or figure out what he wrote months (or years)
later. Sooner or later, if you own a computer you will write
your own program. You may want to use it. sell it. or just
modify or expand it. In any case, you need documentation.
The simplest form of documentation.is usually a descriptive
title, but that is useless for the first reason and inadequate
for the second and third. Heavily commented programs
(with many REMarks) can usually satisfy reason 3 since the
hardware configuration is not often changed, but this
requires a lot of memory for the remarks and may still be
gibberish six months after the logic flow is forgotten.

To avoid this trauma amd make your software useful or
marketable, a few guidelines may help. Since the Color
Computer popularity has flourished, software is coming out
of the woodwork, which makes us all very happy. On the
other hand, if the software is good (no matter how good) but
we can't use it, it is worth no more than the magnetic
domains where it's encoded. From experience as a software
user and software author I've compiled (no pun intended)
eight steps for generating software documentation. Nor-
mally, if you document these items in order, you will have
produced an acceptable document for your work. This may
seem like common sense, but just page through the manual
for the latest utility program you bought or wrote. If it
doesn't cover the first seven points, it is missing something.

(Robert Tyson holds a doctorate in physics and
designs and analyzes high energy laser beam control
systems using computer simulations. He and his fam-
ily live in Jupiter, Fla.)

Guidelines For Documenting Software

1) What is the purpose for it?

Why does it exist, what does it do? Does it speed up file
sorting, or docs it provide entertainment?

2) In general, how does it work?

No details, but is it a printer utility that uses dot-
addressable graphics or is it a real-time Adventure game
where you respond interactively?

3) What are the hardware and operating system requirents?
Does it use I6K non-Extended BASIC, a CoCo, and a
tape, or is it a 64K FLEX program with a printer and
modem optional?

4) What are the input and output formats and ranges?

Does it require one or two word commands with eight
letters maximum? Docs it allow floating point numerical
entry with only graphics output? Or. is it menu driven?

5) How do you make it run and what are your options?

Must you POKE 25, 6: NEW before loading or just insert
the disk and type RUN "A"? What can you do if you get
an overflow error; can you recover the data?

6) What is the runtime?

Does the game take four hours to play? Docs it take 20
seconds to check memory and then load prior to seeing
action on the screen?

7) What is the accuracy?

Does it numerically calculate to 10 decimal places or is
integer arithmetic used? Will the joystick display "dead"
zones?

8) What arc the detailed functions and algorithms used?

Do not include this if it is copy protected or just for user

operation.

Does it calculate the arcsin(x) by a series of 30 terms?

Does it overlay memory onto the memory area for screen

display and rapidly shift graphics pages for the Hashing

display? Which RAM hooks docs it use?

130

the RAINBOW February 1984

Commercial software documentation often includes only
the first five points. Authors may argue that runtime and
accuracy are irrelevant for graphics games, etc.. and they
may be right, but why not tell the user that "the photon
torpedo responds slowly to the fire button and you must
lead the target."

Listing I is a short program to key into your computer.
The following is an example of documentation which covers
the points I've addressed and could be used as a model for
vour own documentation.

This program calculates the factorial of a number. It can
be used as a stand-alone program or as a subroutine in
another BASIC program. The program accepts input from
the keyboard and outputs to the screen only. A Color Com-
puter. 4K. non-Extended BASIC, is all that is required.

Factorials exist only for zero or positive integer numbers.
The program accepts inputs between and 33. Error mes-
sages will occur otherwise. The integer part of a positive
non-integer input is used. After keying in the program, type
RUN. The computer will prompt you for input or errors.
For all values the factorial will appear "instantaneously."

Color Computer display capability is nine significant dig-
its; all results were checked against tables and verified to be
accurate to eight significant digits. The program uses lines
10-30 to input the data and line 40 for checking the validity
of the input value. Since 0!=I!=1. a flag is set in line 50.
Lines 60-90 do a brute force calculation of the formula
x!=(l)(2)(3) . . . (x). Lines 100-120 check for the zero flag,
output the results and loop to the beginning. Press [Break]
to terminate the program. —

SCHOOL IS IN THE HEART OF A CHILD

A Joyful Family Experience

By Fran Saito

and
Bob Albrecht

A wise dragon once said, "School is every-
where and learning is something you can
learn to do. "

— Laran Stardrake

Hello, and Welcome

A long time ago, in a galaxy nearby, the home was the
center of learning. Parents and children worked together to
pass on knowledge to daughter and son. What was not
learned at home was commonly learned by becoming an
apprentice who learned from a master. There were few
"schools, "institutions devoted to teaching instead of learning.

Time passed and schools flourished. In the USA today,
schools are becoming increasingly less adaptive to a chang-
ing world. Fortunately, something is happening, something
that provides rich and highly motivating environments for
learning, outside of schools. Millions of people are buying
computers for home and personal use. Within a few years
nearly everyone will have a computer. There exists an
unprecedented opportunity for learners to take control of
the means of learning.

As learning moves out of the school into the direct control
of learners, once again people are enjoying learning as an
adventure. For themselves, their families, their friends and
neighbors. Through the use of a home computer, the entire
family can work and play together to learn anything from
the mundane to the most esoteric subjects, and on a schedule
and at a pace chosen by the learners.

"School Is In The Heart of a Child" is for parents of quite
young children. We want to help you work and play with
your three- to eight-year-old child and learn to use compu-
ters as a joyful family experience. We want to suggest ways
to incorporate the home computer as another means to
encourage your child's independence, growth and control
over his own life; see the pride on her face as she directs the
computer to do what she with deliberation selects; see her
head gears switch to "on" as she progresses step-by-step with
your presence and caring direction.

We will explore (we hope, with your help) the following:

• Specific "leaching" techniques so that the discovery can
be the child's own.

• Critical evaluation of software based on extensive play-
testing in family and related environments.

• Additional resources to consult: books, magazines,
software publishers, networks, etc.

(Fran Saito holds a degree in education from the Uni-
versity of Hawaii and has taught preschool and ele-
mentary students. She feels her inspiration comes
from Mariko. her five-year-old daughter, as she has
watched her child 's curiosity and desire to learn. Fran
also speaks fluent Dutch and Japanese.)

• Suggestions for interludes and fun times away from the
computer (a must!): call the librarian for specific
information; watch a TV program togetherand discuss
it; work together as volunteers in a community project;
take a fall (or spring or winter or summer) awareness
walk. . . .

• Whatever we learn from families we work with in
Menlo Park or from you, our readers, let's pool our
knowledge. Let's share our experiences as we all learn
from our children.

In addition, we will provide many small programs (begin-
ning this issue!) you can type in and use right now, and
information on how to enter and use programs stored on
tape cassettes or diskettes.

Things To Read

One of the best sources of general information on teach-
ing your on children are books by John Holt. We recom-
mend the following titles:

"How Children Fail"
"How Children Learn"
"Teaching Your Own"

Publisher for all three books: Dell Publishing Co., Inc., 1
Dag Hammarskjold Plaza, New York, N.Y., 10017. We
suggest you sign up for John Holt's newsletter about teach-
ing your own kids at home.

"Growing Without Schooling," Holt Associates, 729
Boylston Street, Boston, MA 021 16.

Although written for users of Atari computers, the follow-
ing book has much information we think will be useful to
you.

for Your Home," Reston Publishing Company, 1 1400

Because you own a CoCo, you subscribe to the Rainbow,
a magazine devoted entirely to your computer. We recom-
mend a second magazine, which specializes in . . . well, the
name of the magazine tells you.

"Family Computing," Scholastic, 730 Broadway, New
York, N.Y., 10003, $17.97 per year (12 issues).

If you have a pre-school child, try to get this back issue:

ing for very young children. Fascinating stuff.

Kids Can Teach Computers

The CoCo is a great machine for teaching kids how to use.
program, and enjoy computers. In this section of "School Is
In The Heart of a Child. "we suggest ways in which you and
your children can learn together how to tell the CoCo to do
what you want it to do.

So. grab a kid and help her or him enjoy — and learn to
understand — simple commands and short programs in
Color BASIC. Wc suggest things to do. You explain what is
happening, answer questions, modify our ideas, and enrich
the learning experience with your ideas. But don't do the
typing. Let the kids do the hands-on stuff. Be patient - let
them make mistakes, correct their own mistakes and. espe-
cially, encourage them to experiment!

EXPERIMENT!

Help kids learn to read and understand BASIC. Presto!
Many of them will them leach themselves how to express
themselves creatively in BASIC, as if by

MAGIC!

Some people arc not interested in writing original pro-
grams. That's okay. They can still use and enjoy computers,
thanks to programs written by people who like to write
them.

Perhaps this is part of "computer literacy. "After all. more
people read novels than write novels; more people listen to

music than compose music: more people use inventions than
invent inventions; more people appreciate art than create
art.

Begin

Show your eager young learner how to hook up the Color
Computer to a color TV. We assume you know how to do
this, including selling the TV channel to 3 or 4. Turn on the
Color Computer and the color TV. This is what you might
see:

This is the
CURSOR -

II your screen says Color BASIC 1.2 or Color BASIC 2.3,
that's okay. You have your later versions of BASIC than the
one wcare using. If your CoCo has Extended Color BASIC,
you will see an appropriate message on the screen.

Tell them about the prompt { OK) and the cursor (■). The
cursor continually changes color as it blinks on the screen.
When you see the blinking cursor, it is your turn to do
something.

Type [C][L][S] and press the [ENTER] key. This is what
you see:

YOU HAVE A 32K SYSTEM WITH 64K MEMORY CHIPS ?? ARE YOU STILL BEING TOLD YOU CAN ONLY USE 32K FROM BASIC ??

DON'T BELIEVE IT !!- KEY COLOR SOFTWARE brings you the KEY-264K. An exciting NEW SOFTWARE utility that allows

SS 64K RAM FROrTBHsTC", and with NO HARDWARE MODIFICATIONS REQUIRED! !!

any STANDARD 32K COLOR COMPUTER TO ACCESS

*** Works with CASSETTE based systems! ***

*** Works with DISK based systems! ***

The KEY-264K divides the 64K ram memory into two 32K banks or sides, each of which can be utilized independently
by the. BASIC interpreter, with the ability to switch instantly from one side to the other. IT'S LIKE HAVING TWO
COMPUTERS IN ONE!! Have your BASIC program on one side and keep your variables on the other side, or have your
main program on one side and your subroutines on the other side, or have your program on one side and use the
other side for 4 additional HI-RES pages, or any combination you like. The possibilities are endless because the
KEY-264K allows full communication between sides plus the ability to switch back and forth at will, all from
within BASIC. You could also have different programs in each side and switch back and forth between them using

simple keystrokes, even while the programs are running!! Or run them both at the same time in the
FOREGROUND/BACKGROUND MULTI-TASKING mode. Don't buy that printer buffer yet! With the KEY-264K you can be
printing in the background side while utilizing your computer normally in the foreground side AT THE SAME TIME!!!
Debugging a program? Use either a BASIC command or simple keystrokes to instantly duplicate your program, in it's
present status, on the opposite side. Switch to the opposite side later and pick up exactly where you were before!

For DISK users, the KEY-264K allows you to alternate between DISK and EXTENDED BASIC on the same side with
simple keystrokes. No need to pull your controller or power down. You can be in EXTENDED BASIC on one side and in
DISK BASIC on the other side and still switch back and forth and have full communications between the two sides.

The KEY-264K does this and MORE thru extensions to BASIC. No need to learn a new language! The KEY-264K adds
15 NEJTCuTORDS and 1 function to BASIC, including powerful new BLOCK MEMORY MOVE and GRAPHICS VIEWING commands.

The KEY-264K works on 32K systems with "E\ "F", or even modified 'D' boards and requires EXTENDED or DISK BASIC
with GOOD 54K MEMORY CHIPS! Systems with piggy-back 32K or half-good 64K memory chips WILL NOT WORK! !

Playtesting

ComputerKid, USA puts computers in the hands of kids
in youth organizations, alternative schools, and at home in
order to playtest and evaluate educational software in places
that are learner-centered, instead of teacher-centered.

During 1 983. ComputerKid organized, managed, and
conducted playtesting and evaluations of more than 1 00
items of educational software for Atari computers. Results
appear in the book "Buy a School for Your Home," men-
tioned earlier in this article.

A Basketball Statistics Program For Your CoCo

Right now we arc well into basketball season. Some of
you certainly are playing, coaching or helping. Oth-
ers have family members involved. Or perhaps you
are a fan and supporter of the old Alma Mater. In any case,
someone associated with your favorite teams sits down with
calculator and typewriter after each game for the thankless
task of working up the latest team statistics. Now you can
bring CoCo to their rescue with these two statistics pro-
grams. They require a 32K Extended BASIC machine, but
you can keep the files on tape or disk and can move files back
and forth if you wish.

BSKBINIT is designed to generate the BASIC files and
revise them to start a new season. ENTRDA TA is used to
enter box score data from each game, update the year-to-
date and career records for each player, and print the
updated statistics along with team and opponents totals.
This report is fully formatted in condensed (16.7 characters
per inch) type by a Radio Shack LP VIII printer or equiva-
lent. The formatted report can also be routed to a disk as an
ASCII file for transfer to an automatic typesetter. (The
program was written for the Rainbow's sister publication
SCORECARD which reports on University of Louisville
sports and whose typesetter is set up to read ASCII files
from CoCo disks.)

Start by loading BSKBINIT and choosing I START
NEW CAREER STATS FILE. First, you enter a player's
name in the format "I. Name," that is, first initial, a period, a
space and the last name. This is important since the alpha-
betical sort looks for the last name starting at the fourth

computers and specializes in BASIC programming.

base management program.)

position in a string. If you make a mistake, don't worry. You
can correct any data entered with the EDIT/ CORRECT
EXISTING FILE routine. Also remember the total length
of the name cannot exceed 13 characters — the periods are
there when you enter a name to remind you of this.

After the name is in, the program asks for the career data
for the player starting with "G" which stands for total
number of games played. Hit the [ENTER] key here and the
program assumes there are no games and no career data and
goes to the name of the next player. When there is no career
data, ENTRDA TA maintains a career data file which is
identical to the year-to-date file and only prints career data
on the statistical report when it is different from year-to-date.

The program keeps the data on each player which is
shown in the following list along with item number and
abbreviation as used in the program or on the printed
report.

the RAINBOW February 1984

You can add new players to an existing file at any time.
The new player is put at the end of the list. I strongly
recommend that once you have initialized a file that you sort
it alphabetically and leave it that way for the rest of the
season. The ENTRDATA program makes game data files
which are stored according to the order of the player list at
that time. Adding players to the bottom of the list won't
upset the relationship of player to game data while an
alphabetical sort with added players will. There is a SORT
ON AVERAGE routine in ENTRDA TA that lets you sort a
file that has been saved so the report can be printed starting
with the player with the highest average. Here again, the file
sorted by average should not be saved since it cannot be
related to back game data files.

Data entry is simple, as the category for data to be entered
is the last one to appear on the screen. Simply key in the right
number and press [ENTER]. If you press [ENTER] only, a
zero is entered.

Once you have entered all your initial data into the career
file, edited it as necessary and sorted it alphabetically, save it
to tape or disk. It is now ready to use with ENTRDATA for
game data entry. Now load and run ENTRDATA. When
you choose I ENTER NEW GAME STATISTICS, you are
asked LOAD FROM 1 TAPE OR 2 DISK. The program
expects you to have the tape or disk with your latest file
named CURRSTAT ready. If you use a disk, the newest
version is always saved out over the old version unless you
change disks. I suggest that you let this happen since past
data is of little value and will exist in printed form. But, be
sure to backup the disk after each game. A single "I "or "2"
keystroke starts the loading.

Now you are asked to enter the game date in the format
MM-DD-YY. This will be used as the game file name and
the disk is fussy about what's in a name. An extra "/ " or "."
will bomb the program. I know, since 1 did it. Do just what
the prompts say and slay out of trouble. Game data entry
starts with display of the first player's name and a 3 MIN?
followed by the cursor. If the player did not play, key
[ENTER] and the program will fill out that entry with zeros
and display the next name. When you enter a number, the
program enters a I after I G and displays 2 STAR 1 = 1. This
prompts you to enter a 1 if the player started the game or
simply an [ENTER] if he did not. From here on, data is
entered as you did when you made the initial file.

When data is entered for each player, the opponent's
game stats are requested. These are the box score totals and
not individual player data. This done, the program pauses to
update all its career and year-to-date files. Team and dead-
ball rebound data is now requested and SAVE TO ITAPE
OR 2 DIS K appears. Don't worry about errors in the file. At
this point we want to be sure to get the data that was entered
safe. We can correct later and save an updated version. By
the way. two saves of two files are always made to tape.
CURRSTAT is saved first and then the game file is saved. If
you want to preserve your game files, make sure to use new
tapes each time ordilferent sections of a tape. If you edit an
old game file, be sure to do it with the latest CURRSTAT
file in the machine. Disk drive owners can keep the current
CURRSTAT fileand a season full of game files on onedisk
without problems.

After data is saved, the program returns to the Main
Menu. If there were mistakes, choose 2 EDIT/ CORRECT
CURRENT GAME and get the job done now. As the game
file is edited, the career and year-to-date files are revised as
well. Remember that ENTRDATA automatically makes a

save of the latest files when it leaves any data entry or editing
routine.

With all in order you are now ready to print the statistics.
First, call 5 SORT ON AVERAGE.'This puts the CURR-
STAT file in memory in order by average. As a debugging
aid, the order of the averages is printed each time a swap is
made. If this bothers you, delete line 825. Next, choose 4
PRINT STATISTICS. The next menu you see was bor-
rowed from another program and works differently. Use the
up or down arrow keys to move the pointer to your choice
then key [ENTER]. To change the Baud Rate, move the
pointer to RESET BAUD RATE, key [ENTER] and enter
your new BAUD RATE. The program accepts rates from
1 10 to 4800.

Using condensed type, the entire report prints on one 8/4
x 1 I page. For some applications like school newspapers
and sports newsletters, you may find it suitable for publica-
tion directly. Printer codes used are for the LP VIII and
succeeding Radio Shack nine-wire printers. If you need to
change these, CHRS(27)CHR$(20) in line 625 sets the
condensed type. CHR$(I5) in line 636 starts underlining.
CHRS( 14) in line 640 stops the underlining. Underline prin-
ter codes also appear in line 682.

At season's end. pack your tapes or disks away until next
year. To start off the new season, load last season's final
results into BSKBlNIT&nd choose 6 U PDATE TO STA RT
NEW SEASON. This routine lets you delete graduated
players and zero's the year-to-date file. Add new players, do
the annual alphabetical sort and save the file to the disk or
tape for the new season. If you are on disk, put the
BSKBINIT and ENTRDATA programs on the new disk
and you are ready for the first tipoff.

What's Bothering You
About BASIC?

By Richard A. White
Rainbow Contributing Editor

I occasionally stew over what to write about next. A
friend agreed that 1 have touched many of the principal
basics. And then something comes up and an idea is
born. Well, this month's article got just such a start and was
well underway when some mail came from the Rainbow and
I decided to save what had been written for later and start
fresh. The writers asked some real basic questions that need
answeringand we will do that in this issue. What's bothering
you about basic? Drop me a short note through the Rain-
bow and I may be able to answer your question as well.

Judith Almendariz from Illinois writes as follows. "1 am a
novice with computers ... I find myself extremely frustrated
each lime people allude to PEEK and POKE statements. I
can't find any books which adequately describe what exactly
you are doing when you PEEK and POKE. Where do your
contributing authors find the information as to what to
PEEK or POKE \nlo their programs lo obtain the desired
results'?" Well. Judith, you need to understand how compu-
ters work to really understand what PEEK and POKE do.
You are not alone, there are a whole lot of new computer
owners struggling to understand their machines. Indeed,
why buy a computer and study basic if not to learn how
computers work and how to use them? Computer literacy
comes only from much study and work. So. lei's start the
lesson,

A computer starts with memory. Memory consists of
eleel ronic circuits that can either be off or on. Each circuit is
a "bit." If the circuit is on. the bit equals one. else it is a zero.
You will also see the ON state represented as high (voltage)
and OFF as low (voltage). In any case, only two states can
exist. This is what binary means, two states.

These individual circuits, or bits, are grouped in blocks of
eight which make up a byte. A byte is always eight bits. Bits
in a byte can be set to define any number bclwecn and 255
decimal. For example the byte "00000000" means zero. The
byte "1 1 1 1 1 1 1 1 "means 255. CoCo's memory is divided into
byte-sized memory locations.

There are two types of memory. Read Only Memory,

(Richard While has a long background with micro-
computers and specializes in BASIC programming.
With Don Dollherg, he is the author of the TIMS data
base management program.)

ROM. is made so the numbers arc permanently fixed in the
chip. You can turn the computer off and back on and the
information in the ROM is always there for the micropro-
cessor to use. Random Access Memory. RAM. is change-
able. The microprocessor can put numbers into RAM loca-
tions as well as reading the numbers that arc there. Further.
RAM numbers exist only while the power is on. Turn the
power off and all voltages in the RAM go to zero, destroying
any stored data.

Our microprocessor does all its work by reading instruc-
tion and data numbers from memory and performing the
action which the instruction numbers call for. Data numbers
can mean many things depending on the program. These can
include data addresses in memory, calculated numbers or
numeric representations of characters.

Now a PEE K statement does nothing more than look at a
memory location and return in decimal form the number
contained in the byte stored there. Type in PRINT PEEK
(15(1). If you just started up your machine, an 87 will appear
on your screen. You told CoCo to print the value stored in
memory location 150. What does an 87 in memory location
150 mean to CoCo? When CoCo goes to send data to the
printer, it needs to know the Baud rate or how fast to send. A
routine in BASIC manages this transmission. It instructs the
microprocessor to get the number in location 150 and use
that number to determine how long each bit sent the printer
should be.

POKE allows you to put a number ranging from to 255
into a memory location. If your printer is set up for 1200
Baud, the number in location 1 50 should be 4 1. You need to
set that with the statement POKE 150,41. PEEK and POKE
can work with all the 65535 bytes that the microprocessor
can address. What happens depends on what kind of
memory or register is at the location addressed. PEEK wiW
return a valid number from any address where there is ROM
or RAM memory installed. It will even return numbers from
PEEKs to addresses where there is no RAM. These arc
meaningless. A POKE to a RAM address will put the
number into that address. Nothing happens when a number
is POKEd to a ROM address or to an address where no
memory is installed.

Where do you find what to POKE'! The POKEI50.4I
comes right out of the Color BASIC manual. Spectral Asso-

TRS-80 Color Computer. TDPSystem 100.

THE STORIES ABOUND that there
will be yet another Color Computer, or
at least, another version of the CoCo
within several months. We hear that
from a number of places, but we also
hear that the chances of any major mod-
ificationsare not really very likely in the
near future. Part of the rumors, obvious-
ly, are "scrambled" from word that
leaked out on the new Tandy TRS-80
2000 — a "color computer" in that it has
high resolution graphics and colors avail-
able. But this new computer from Tandy
— a very sophisticated machine, by the
way — is aimed at a very different
market. With the rumors flying, it was
easy to see how some things might have
gotten a bit mixed up. Yes, we do see
some changes in CoCo, but the chances
are that, at least for the moment,
those changes will be ones that will
evolve in steps rather than by dramatic
leaps.

Speaking of the Tandy 2000. it is an
excellent machine which out lBM"s
IBM. Comments at the recent COM-
DEX show where it was unveiled were
almost 100 percent enthusiastic. Intact,
the 2000 may well be the state of the art
personal business computer of the year.
It is certainly a brighter contender for
the honors than the new IBM entry, the
PCjr., or "Peanut," which also was at
the show last month.

• * *

ONE OF THE HOTTEST buzzwords
in the computer software field these
days is "Windows," with the leader
obviously being Microsoft, which has a
program by that specific name. What a
window is is a program which allows
you to put several different "screens"
from several different programs on the
monitor at the same time. What with the
Hi-Res capabilities of the CoCo, we
would not be surprised to see some
"Window" programs being offered for
this market before very long. One of the
things, though, that we thought landed
in the "missed the boat" area as far as
Microsoft's promotion was concerned
was failure to recognize an opportunity
to coin an old saying in selling their
Windows program: "We do do Win-
dows."

YOU DONT OFTEN READ news
about other Color Computer publica-
tions on these pages, simply because we
do not make it our business to comment
on anything which might be considered
to be partisan in nature. But we have
received a number of letters on the sub-
ject and we feel it only fair that you
know that it is out understanding that
Color Computer News is ceasing publi-
cation and that Hot CoCo has agreed to
fulfill the outstanding CCA' subscrip-
tions. From what we hear, that means
CCN subscribers will get issues of Hot
CoCo until their CC/V subscriptions run
out.

MARKETING THESE wonderful
machines we use in our work and play is
at the heart of industry health, and so
when we found a recent Radio Shack
news release announcing the promotion
of Ron G. Stegall to senior vice presi-
dent, computer marketing, we very care-
fully penciled "Pipeline" at the top of
the page. We're pleased to recognize this
step up for Ron to a position so closely
related to the health and well-being of
all of us. In his new capacity, Ron will
be respon ;ible for the overall marketing
effort of the more than400 Radio Shack
Computer Centers and more than 630
Radio Shack Computer Departments
nationwide, as well as other account,
education and procurement duties.

And while we're speaking of new
Radio Shack vice presidents, we should
mention William D. Gattis's new ap-
pointment to the position of vice presi-
dent, Radio Shack Education Division.
He will be responsible for the develop-
ment and overall marketing of micro-
computer products, instructional soft-
ware and courseware systems for educa-
tional applications. Congratulations to
both of these gentlemen, and our thanks
for the job they have done for the Color
Computer and the industry.

WEST COAST ROCK fans are devel-
oping modemania. it seems, as Portland
rock station KGON 92FM has begun
operating a new BBS for hard-rock
hackers, or "user-listeners" as the sta-
tion says.

The KGON BBS will initially consist
of a dozen menu options including not
only the top 40 rock songs in the Port-
land area, but the top 10 software sales
and the top 20 videocassette rentals.
News, rock news and concert reviews, as
well as an E-mail service, will also be
available to those calling KGON's data
line at (503) 655-9 18 1 . And what would
the West Coast be without its preoccu-
pation with lifestyle? Well, it would still
be beautiful, but nevertheless, lifestyle
information is yours for the dialing, too.

The operational hours for KGON
BBS are from 6 p.m. to 6 a.m. Monday
through Friday, and around the clock
on weekends and holidays. Sysop Chris
Burns, who is also KGON's news direc-
tor, informs us that calls are limited to
15 minutes. The system is comprised of
a 64K Color Computer, two Radio
Shack disk drives, and a Hayes Smart-
modem 300. Give 'em a call. Long live
Hack N" Roll!

inate the problems of poor contact that
often cause such things as directory
errors and inaccessible data. We're speak-
ing of a disk module kit called Gold
Plug-80.

Ground tab extensions are included
in the kit which extend the ground tabs
far enough to contact the ground clips
on the CoCo female connector, reduc-

dates' book, "The Facts" is full of memory locations and
their contents. Bob Russell's "Color Computer" Memory
Map appeared in four installments in the 1983 issues of the
Rainbow and may be ordered for $9 (Bob Russell, 5474
Stillwater Court, Fredonia.Wis. 53021). These are good
references, but to know that the cursor color is stored at a
certain location doesn't help much if you are not interested
in changing the cursor.

A better way is to follow the programming articles and
hints in the Rainbow and see where authors are PEEKing,
POKEing, why they are doing it and what kind of results are
obtained. PEEKs and POKEs are not as important to CoCo
as they are to competing machines. For example, we have
BASIC commands for graphics while Apple, Commodore
and Atari need to POKE numbers to get similar results. And
why remember to POKE65313.4 to turn the cassette motor
on when the BASIC command MOTORON docs the same
thing easier? Oh, you just had to try it, did you, and now
MOTOROFFwon'l turn the cassette off? POKE65313.52.

1 hope that helps, Judith. You even got the tutorial you
wanted.

"Note that in all of this, that the guiding
principle is what makes it easiest for you,
the programmer."

F. Bruhns from California asked for an article on the ins
and outs of multiple statements under the same line number
including what works and what does not. A well stated
request, so here goes. Line numbers are used by BASIC to
define the start of a block of code. They are particularly
important in defining the targets for GOTOs and GOSUBs
and line calls after THEN. A line number may be thought of
as an address. Think of two houses, one where a single
person lives and one where there is a big family complete
with grandparents. The mailman delivers mail to a single
mailbox in each case. It generally does not matter how many
live in the house. In BASIC this is true as well in that one or
many statements may be on a line.

Now should the grandparents have a separate entry and
part of the big house and wish to get their mail directly, they
would put up their own mailbox and have a separate
address. We would put them under a different line number
so their mail can GOTO them directly. So, subroutines and
code blocks that are targets of GOTOs elsewhere in the
program start with separate line numbers.

Just as many people can live in a house, many statements
can be under a single line number. Each is separated by a
colon (.). The limit is the number of characters the keyboard
buffer will accept. I count 249 characters. You can stuff even
more if you use a program like Eigen's Stripper which
combines lines of tokenized basic.

Aftcryouentcra line, it goes through a tokeni/.ing process
that converts all keywords like PRINT, POKE. INPUTelc,
to one or two numbers unique to each. Obviously, fewer
bytes are needed to store the tokenized line of code, and
Stripper simply combines tokenized lines within certain

rules to fill out to 250 bytes capacity. Five more bytes are
used for the line number, the address of the next line in
memory and the at the end of the line.

One rule is that a line called by a GOTO or a GOSUB is
not added to the line above it. Another is that a following
line cannot be added to the line above when the first line
ends with an IF/ THEN statement. IF/ THEN is a control
structure that is managing program action. One action can
be to fall to the line below if the test made after /Fis untrue.
Obviously that could not happen if the statements in line
below were instead after the THEN. So think out what is
happening after IF/ THEN statements. And while we are on
IF/ THEN/ ELSE, no colon is used after /For on either side
of THEN or ELSE.

In some instances quite a bit of code is needed after THEN
and ELSEio get all the work done that is needed. Resist the
temptation to keep the line short by putting the statements
in the line below which you then have to be jumping over. 1
think it is easier to trouble shoot program logic if all code is
in one line.

I know what you are thinking. If a line has fifteen state-
ments in it. how do 1 find which one caused the Syntax Error
or whatever bombed in that line? One way is to edit a
number of STOP statements into the line. Each time BASIC
meets a stop it stops the program and says BREAK IN XYZ.
When you type CONT, basic will pick up with the code
after the STOP. If you put three STOPs in a line and get two
BREAKs and then the SN ERROR, you have narrowed
your problem to only that code between the second and
third STOP.

Multiple statements in a line save memory. Remember
each line of BASIC in memory has two bytes for the line
number, two bytes for the address of the next line and theO
at the end. Each time you can combine two lines into one,
you save five bytes. When you combine 10 lines into one,
you save 50 bytes. The savings can really mount up and the
program will run faster, too.

While we are talking about line numbers, what is sacred
about spacing lines 10 apart? This leaves room for adding in
new code later if needed. 1 like small line numbers. It takes
one byte less to GOTO 100 than to GOTO 1000. 1 like
GOTO 10 even better.

Don't feel that when the program is done you need to
renumber to get back your spacing of 10 line numbers. This
is more harmful than helpful if you need toedit later. Asyou
wrote the program you got used to certain things being at
certain lines and now RENUM will change all that. 1 assign
blocks of code to line number blocks of 50 or 100 and even
write at spacingsof two to get in all I need to. As I work up a
program. I know exactly which block to go to to change
something. For example, 1 always put a main menu at 1000
and tape and disk I/O between 900 and 1000. When the
program is done I may RENUMO.0,1 to start the program at
lineO with spacing of 1. This uses least memory. 1 make sure
to save a copy of the program before I do a RENUM. If
problems develop later I go to the "uncompressed" version,
edit it and then RENUM it to get a new working version.

Note in all of this, that the guiding principle is what makes
it easiest for you, the programmer. CoCo could care less
how far the lines are spaced or what's in them as long as
syntax is right. Also CoCo is not concerned about program
logic, but just does what it's told. If you find it easier to line
number at intervals of 10 and put only one or two statements
per line, then that is the right way for you.

Will they shoot?"

Basket was created by this fan with the above ideas in
mind. It is not the ideal solution, but 1 think it does aim in
the right direction. This is not a fancy program, nor a pretty
one. You'll find subroutines popping up like weeds all
through it. Like my garden, it wasn't planned that way.
That's just how it grew.

You can play either a college or a high school version.
First, PCLEAR /, then load and RUN the program. For
each team you will be asked to enter ratings in four catego-
ries: outside shooting, inside strength, defense and quick-
ness. In each case the ratings should be in the range of .3
(poor) to .7 (best), with .45 to .5 as the average.

"Outside shooting" represents the general shooting per-
centage of the guards, whose range is considered to extend
to 20 feet. "Inside strength" roughly corresponds to the
height and strength of the team's center and forwards. It
represents their shooting percentage within 10 feet (except
for shots under the basket) and their rebounding ability.

The defense rating is used alone when the team is in a zone
defense (lines 80 10-80 1 1 ) and combines with quickness for a
man-to-man defense (8200-8201). Quickness and defense
also determine a team's ability to drive to the basket (8640).
Defense combines with inside strength on defensive rebounds
(3030-3040) and quickness affects turnovers (5 1 3-5 1 6. 1 025).

After the ratings are entered you will see an empty score-
board and statistics chart showing field goals attempted
(FGA), field goals (FG), free throws attempted (FTA), free
throws (FT), rebounds (RB) and fouls. This chart will
appear after each period, and can be viewed before shooting
free throws. After play starts, the list also will contain turn-
overs (TO), field goal percentage (FG PCT) and free throw
percentage (FT PCT).

Next, you can select to coach both teams (two-person
game), coach vs. CoCo (one-person game), let CoCo play by
itself or let CoCo play until the final few minutes.

If you choose option 2, you will coach team I while the
computer makes the decisions for team 2. In option 3, the
computer directs both teams.

If you choose the last option, you will be asked, "How
many minutes?" That is, at what point do you want the
computer to hand the coaching duties over to you? Then you
will be asked. "Switch to which mode?" Select I or 2. coach
both teams or coach vs. CoCo. (When the clock gets to the
point you specified, the program will pause to tell you it is
time to change modes.)

Once the game starts, the action keeps moving. If no
option is selected within a certain length of time when an
option menu appears on the screen, the program will select a
default response and continue. (When the computer is
coaching, of course, it will make decisions of its own.)

The length of time can be varied by pressing the up arrow

to speed up the program or the down arrow to slow it down.
This works only when the clock is running, or when the
message is on the screen before each period. Note lines 9
through 1 1, the delay subroutine. Each time through, line 10
checks for the arrow keys and adds to or subtracts from DL
accordingly. DL determines the length of the FOR/ NEXT
loop in Line 9.

As the game starts, the top line on the screen will identify
the team with the ball (we still have the old jump ball before
each period). The second line will show what alignment the
defensive team used the previous time down the floor. This
will be blank the first time, of course.

Below this will appear a prompt for the defensive coach to
select a defensive alignment. If he makes no choice within
the time limit, the defense used last will be retained. The
prompt line looks like this:

(TEAM NAME) MAN (1-7), ZONE (2-8)

GO FOR BALL (3-9), OR FOUL (0-4)

(Foul and go for ball are for desperate situations.)

Here's what those numbers mean: The player directing
team I will use keys 1 . 2. 3 and 4 to make his selections. The
player directing team 2 ( if any) will use keys 7,8,9 and 0. It is
up to the players to keep track of who is on offense and who
is on defense. I've found the game works best if the defensive
player keeps his hand off the keyboard except when he needs
to make a choice.

After the defensive choice is made, the screen will clear,
the top lines will reappear and the computer will tell whether
the ball is in the hands of a guard ora "big man"(center or
forward), how far he is from the basket and whether he is
open or guarded. Below this you will see:

February 1984 the RAINBOW 163

(3-9) TO PASS

1 f no choice is made within the time limit. Pass is selected.
Both players use the space bar to shoot. Free throws are shot
automatically. You'll hear a "beep" when points are scored.

Passing is most effective against the zone defense; driving
is most effective against a man-to-man. Shooting is most
effective when the ball-handler is open and within 20 feet for
guards or 10 feet for big men.

If a shot is good or the ball is turned over out of bounds,
the screen will clear to orange to indicate the ball changes
hands, and the new defensive team will be asked to choose
among fall back, press, go for the ball or foul. The default
choice is fall back. If the ball does not go out of bounds when
it changes hands (defensive rebound, for instance), this
option is not available.

Missed shots sometimes are tipped back up automati-
cally, sometimes are knocked to the backcourt. and some-
times result in fast breaks that lead automatically to layups.

After a team commits 20 fouls, and every five fouls there-
after, it is arbitrarily assumed that a player has fouled out,
and the team's defensive rating and either the outside or
inside ratings drop .05 each. If the program says player 1 or2
has fouled out. a guard leaves and the outside rating drops.
Otherwise, a big man leaves and the inside rating drops.

That's about all you need to know to play Basket. You'll
find that sometimes scores seem to go against the ratings; a
poor team upsets a good one, or two evenly matched teams
can end up 20 points apart. But this can happen in real
basketball, too. and much depends upon the player's strat-
egy and shot selection. And then, sometimes you get the
breaks and sometimes you don't. That's the way the key-
board bounces.

In the fantasyland of magazine publishing, a
columnist becomes trapped in a time warp that
serves up a St. Valentine 's Day turkey, compresses
a contest, and causes dragons and other unlikely
characters of old to pour forth from a 20 th century
machine.

Welcome to Fantasyland! As you know, there is a
contest going on in this column to design spells
and monsters for the new fantasy roleplaying
game we are creating. The response so far has been excellent,
with several really good entries, and we will be announcing
the winners in next month's column. If you haven't already
entered, it is probably too late now, but if you want to give it
a try the rules and prizes are in last month's issue. The reason
it's too late is called lead time, and 1 never appreciated it
until lately. The cover of this magazine may say "February,"
but as I sit here at my trusty CoCo pecking out these
immortal words in an effort to beat my deadline, my
calendar says that Thanksgiving is just a few days in the
future. If sometimes we don't seem as timely as you would
like, that is the reason.

This month we are digressing for a bit. A lot of people
have written me and asked for a complete character
generator program to use with Dungeons and Dragons, and
so 1 decided that I would provide the one 1 use myself. This is
a complete package, and lets you create a character thai
includes basic scores, race, class (or classes), sex, age, height ,
weight, thieving abilities, clerical spell bonuses, and hit
points. Try it out a few times, and I think you will be
pleasantly surprised by the accuracy and attention to detail.

By the way, this program rolls up characters for use with
fantasy roleplaying games. It isn't a game itself. I say that
because lots of people have typed in one of my programs and
then called or written to say that they didn't understand how
to get the game to start.

Next month we will have the winners in the monsters and
spells contest, and we will also continue with the develop-
ment of our new game — really, 1 promise. So, until then,
you have a nice St. Valentine's day, and I'll go pick out a
turkey. I sure am glad I don't really have to take my trusty
sword Doomspeaker out and slay my own turkey again this
year, but that's another story.

(Bill Nolan and his wife Sara operate Prickly- Pear
Software. Bill also teaches computer science at a local
college and is DM at a regular weekly fantasy game.)

The HJL-57 Keyboard

Compare it with the rest.
Then, buy the best.

If you've been thinking about
spending good money on a new
keyboard for your Color Computer,
why not get a good keyboard for
your money?

Designed from scratch, the
HJL-57 Professional Keyboard
is built to unlock ALL the
potential performance of your
Color Computer. Now, you can
do real word processing and sail
through lengthy listings. ..with
maximum speed; minimum errors.

At $79.95, the HJL-57 is reason-
ably priced, but you can find
other CoCo keyboards for a few
dollars less. So, before you buy
we suggest that you compare.

Compare Design.

The ergonomically-superior
HJL-57 has sculptured, low-
profile keycaps; and the three-
color layout is identical to
the original CoCo keyboard.

Compare Construction.

The HJL-57 has a rigidized
aluminum baseplate for solid,
no-flex mounting. Switch contacts
are rated for 100 million cycles
minimum, and covered by a spill-
proof membrane.

Compare Performance.

Offering more than full-travel,
bounce-proof keyswitches, the
HJL-57 has RFI/EMI shielding that
eliminates irritating noise on
displays; and four user-definable
function keys (one latchable),
specially-positioned to avoid
inadvertent actuation.

Free Function Key Program

Your HJL-57 kit includes usage
instructions and decimal codes
produced by the function keys,
plus a free sample program
that defines the function
keys as follows: F1 = Screen
dump to printer. F2 = Repeat
key (latching). F3 = Lower case
uppercase flip (if you have
lowercase capability). F4 =
Control key; subtracts 64 from
the ASCII value of any key
pressed. Runs on disc or tape;
extended or standard Basic.

Compare Installation.

Carefully engineered for easy
installation, the HJL-57 requires
no soldering, drilling orgluing.
Simply plug it in and drop it
right on the original CoCo

mounting posts. Kit includes a
new bezel fora totally finished
conversion.

Compare Warranties.

The HJL-57 is built so well, it
carries a full, one-year warranty.
And, it is sold with an exclusive
15-day money-back guarantee.

Compare Value.

You know that a bargain is a
bargain only as long as it lasts.
If you shop carefully, we think
you will agree. ..the HJL-57 is
the last keyboard your CoCo will
ever need. And that's real value.

Order Today.

Only $79.95, the HJL-57 is
available for immediate shipment
foreitherthe original Color
Computer (sold prior to October.
1982) or the F-version and TDP-100
(introduced in October, 1982).

A REAL SPREAD-SHEET PROGRAM FOR THE COLOR COMPUTER

TM

DYNACALC

Business people use spread-sheets to organize columns and rows of figures.
DYNACALC simulates the operation of a spread-sheet without the mess of paper and
pencil. Of course, corrections and changes are a snap. Changing any entered
value causes the whole spread-sheet to be re-calculated based on the new
constants. This means that you can play, 'what if?' to your heart's content.

But DYNACALC isn't just for accountants. DYNACALC can be used for just
about any type of job. Not only numbers, but alphanumeric messages can be
handled. Engineers and other technical users will love DYNACALC s sixteen-digi t
math and built-in scientific functions. There's even a built-in sort command,
so you can use DYNACALC to manage small data bases - up to 256 records.

DYNACALC will let your computer do just about anything you can imagine.
Ask your friends who have VisiCalc, or a similar program, just how useful an
electronic spread-sheet program can be for all types of household, business,
engineering, and scientific applications.

DYNACALC is designed to be used by non-programmers, but even a Ph.D. in
Computer Science can understand it. Built-in HELP messages are provided for
quicK reference to operating instructions.

DYNACALC has a beautifully, simple method of reading and writing FLEX data
files, so you can communicate both ways with other programs on your system, such
as the Text Editor, Text Processor, Sort/Merge, RMS data base system, or other
programs written in BASIC, C, PASCAL, FORTRAN, and so on.

Except for a few seldom-used commands, DYNACALC is memory-resident, so
there is little disk I/O to slow things down. The whole data array (worksheet)
is in memory, so access to any point is instantaneous. DYNACALC is 100$ 6809
machine code for blistering speed.

Color Computer DYNACALC works with the FLEX operating system from Frank
Hogg Laboratory (64k required). If you aren't already using this powerful
operating system, we have a special deal for you: order DYNACALC (regularly
$200)- and FHL Color FLEX (regularly $99) together for only $250.

To order, see your local DYNACALC dealer, or order directly from CSC at the
address below. We accept telephone orders from 10 am to 6 pm, Monday through
Friday. Call us at 314-576-5020. Your V I SA or MasterCard is welcome. Be sure
to specify that you want the Color Computer version.

Cheapstick — A Smooth,

Rugged Joystick For

Less Than $10

By J.D. German

If your Color Computer joysticks have as many miles on
them as mine do, they probably suffer from the same
malady — mechanical backlash caused by wear and
stretching of the plastic guides inside the mechanism. Back-
lash is the name engineers give to looseness or play between
moving parts, and is a major design problem in mechanisms
like steering systems, radio tuning dials, and gearsystems. In
your joystick, backlash makes playing those high resolution
arcade games a very frustrating experience, because you
cannot get the fine control you need. Until now, the solution
has been to buy a new set of Radio Shack joysticks every
100,000 alien spacecraft or so, or to spend $40 to $60 for a
joystick based on a high-quality mechanism like those used
in radio control transmitters. But, if you are moderately
handy with a drill and a soldering iron, and you have an
hour to spare, you can make a smooth, accurate joystick for
less than S 10.

All the parts you will need for this joystick (which 1 call
Cheapstick for obvious reasons) come from the same people
who sold you your old, worn out joystick; Radio Shack.
Unfortunately (for us). Radio Shack does not sell the joys-
tick plugs or cables. But if you are building your Cheapstick
as a replacement for a worn out joystick, you can use the
cable from it. If not, you might have some luck finding a
plug at a local electronic parts store. Ask for a five pin male
DIN connector with a 240 degree pin spread. You may wish
to take your old one along to be sure of a match.

All of the other parts you will need, along with the Radio
Shack part numbers, are shown on the parts list. The total
price for these parts as listed in the latest Radio Shack
catalog is $8.52. If you want to substitute parts from your
junkbox or a source other than Radio Shack, any joystick
mechanism with I00K potentiometers, any normally-open
momentary contact switch, and any box that will hold them
both will do.

To prepare the box for mounting the joystick and switch,
you will need to make two holes in the box and five holes in
the cover. The holes in the box are for the cable and the

(J.D. German, a private consultant, has authored sev-
eral educational programs which are marketed through
his consulting firm. Creative Technical Consultants.

and is a former associate professor at the U.S. Air
Force Academy.)

switch, and are located as shown in Figure 1 . These locations
were selected on the basis of my own personal preference
and could easily be changed to suit yours. The holes in the
cover are laid out as shown in Figure 2. The large hole can be
made easily with a % inch round chassis punch, but a large
drilled hole followed by some fancy work with a file will also
do the job. If you use the file method, trace the % inch circle
onto the aluminum cover with carbon paper so you will
know when to quit filing.

After you have finished making the holes, you are ready to
install the cable; but a word of caution here. If you are using
the cable from an old joystick, cut off the portion that was
inside the joystick box. The cable is often damaged by
flexing at the point of entry, causing an intermittent open
circuit in one or more of the wires. Before installing the
cable, strip the sheath from the last three inches of the loose
end, but be careful not to cut the insulation on any of the
wires just beneath the sheath. Then strip the insulation from
the last Vi inch of the five wires and tin them by briefly
heating them with a soldering iron while applying a little
solder. Finally, install one of the small strain-relief bushings
four inches from the cable end and push the bushing into the
cable hole in the box. The large end of this bushing goes on
the outside of the box. The last step before wiring the
joystick is to mount the switch in its hole with the hardware
provided.

The new joystick, with its all-metal mechanism and wide
stop collar, is a great improvement over the old Color Com-
puter joystick and should withstand many times the abuse
without developing backlash. The wiring is quite simple if
you follow the drawing in Figure 3. First, solder the white
and black jumper wires in place from pot terminals VI to H3
and from H I to V3,and then solder a 2-inch long black wire
to terminal V 1 . You can use pieces of wire from the cut off
end of the old cable for this if you avoid the sections that
were pinched where they enter the box. Finally, solder the
five wires from the cable to the pot and switch terminals as
shown, and solder the black wire from terminal VI to the
other switch terminal. Be sure to follow the wire color
coding shown in the figure or your pac clone will become
very confused, and there are some wrong connections that
could damage the power supply in your computer.

Afteryou attach thejoystick mechanism to the box cover
and put the cover on the box, you are ready for a test flight.
Since the new mechanism is so smooth, it will take you a
game or so to get used to it, but once you do, your scores.

the

RAINBOW
J- -t

This month I would like to present a simple assembly
language utility to make your BASIC programming
just a little bit easier. Are you interested? It will work
on any Color Computer with at least 4K. Disk drives and
Extended Color BASIC are strictly optional.

Introducing Keyboard Shorthand. This is a short routine
that you load in from tape or disk when you first turn on
your computer. It modifies the keyboard control system so
that each of the alphabetic keys A to Z has a special abbrevi-
ation. To invoke that particular abbreviation, just hold
down the arrow key and hit the proper letter key. For
example, holding down the down arrow and pressing G will
cause the word GOSUB to appear on the screen. This will
have the exact same effect as pressing each of the keys
individually: G-O-S-U-B.

Each of the 26 alphabetic keys has one such abbreviation,
and you may easily redefine them however you like. (We'll
talk more about that later.) So, writing a BASIC program
with Keyboard Shorthand becomes quicker because you
have to hit a lot fewer keys. Also, you will be able to cut
down on the number of errors due to misspelled BASIC
statements.

The source code for Keyboard Shorthand is shown in the
listing. You may enter it on any standard editor assembler
package, such as Radio Shack's EDTASM+. The code as
shown is for a 32K system. If you have 1 6K, change the ORG
statement to S3E00. If you have 4K, change it to $E00.

Once you have finished entering the source code, check
your work for typographical errors. Then assemble it onto
tape or disk. Finally, save the source code to tape or disk as
well. This is done just in case you ever wish to make any
modifications at some time in the future.

Now, you are ready to program in BASIC with Keyboard
Shorthand. Turn on your computer and enter the command
CLEAR200J2256. This tells BASIC to leave a certain area of
memory alone. This area will be used by Keyboard Short-
hand. If you have a I6K system, enter CLEAR 200,1 5872. If
you have a 4K system, CLEAR 200.3584.

Next, load in Keyboard Shorthand and EXEC'it. BASIC'S
OK prompt will immediately reappear, and everything will
seem to function normally. Indeed, everything will function
normally, until you hold down the down arrow key.

Holding down the down arrow key tells Keyboard Short-
hand to do its thing. If you then press an alphabetic key, the
corresponding abbreviation will appear on the screen instead
of just the usual letter.

Holding down the down arrow key and pressing [ENTER]
will cause a list of all the alphabetic keys and their abbrevia-
tions to be displayed. This is handy if you forget for a
moment which key does what. The prompt "Press Enter to
Continue" will appear at the bottom of the screen under the
abbreviations list. Pressing [ENTER] will cause the screen
to clear and OK to appear in the upper left corner. Please
note that if you were in the midst of entering a program line,
it will be lost.

the University of California at Berkeley, enjoys work-

bow. He also designs and translates programs for

Also note that to implement an abbreviation or to print a
list of abbreviations you must hold down the down arrow
key as you press the other key. This works in much the same
manner as you hold the [SHIFT] while pressing the semi-
colon to produce a plus sign.

By the way. Keyboard Shorthand is written entirely in
position independent code. This means that it may be placed
anywhere in memory and it will still work properly. This
allows you to use the offset load feature of CLOADM and
LOADM. Just remember to alter your CLEAR command
accordingly.

Are you curious about how Keyboard Shorthand works?
If you are, then here is a brief explanation:

Keyboard Shorthand patches itself into the keyboard
input routine so that whenever BASIC wants to wait for you
to type something, it will call on Keyboard Shorthand's
special routine, instead of the regular routine contained in
the ROM.

Keyboard Shorthand calls on the regular input routine
(the one located at [SA000]) to see if a key is pressed. It then
checks to see if the down arrow key is being held down. If it is
not, then everything is very much business as usual.

If, however, the down arrow key is being held down, then
A>i7'ofl''^S/7or//;«;j^take.sacloseiTookal that key you just
now pressed. If it is the[ENTER] key. than an abbreviation
list is printed.

If it is an alphabetic key. then Keyboard Shorthand \ooks
up the proper abbreviation in the table. The memory loca-
tion of the first character of the abbreviation is stored in
PNTR. Also, STATUS is set to a value of one. (It usually
has a value of zero.)

keyboard input, it will note that STATUS is not zero.
Instead of scanning the keyboard as usual, a character will
be read from the abbreviation table and PNTR will be
bumped up by one so that it now points to the next character
in the abbreviation. Keyboard Shorthand"spoon feeds" the
abbreviation to basic one character at a time like this until
the whole abbreviation has been completed. Then STATUS
is reset to zero, and Keyboard Shorthand goes back to
functioning normally.

Earlier I talked about customizing the abbreviations. You
may change the FCC instructions in the abbreviation table
in any manner you please. An abbreviation may be as com-
plex as you like, and may even contain multiple BASIC
statements like:

PRINT#-2."DISK DIRECTORY":POKE 1I1,254:DIR0

You may also have the abbreviation automatically hit the
[ENTER] key for you. You do this by adding an FCB 13
instruction (look at R for an example). When you add
[ENTER] to an abbreviation, it appears on the screen as
usual, but begins executing right away. Holding down the
down arrow key and pressing R. for example, causes RUN
to appear on the screen and the program to begin running
immediately.

Your abbreviations may be as specialized, long, and fancy
as you wish. However, if you make them much longer than
they arc as shown in the listing, you will need to lower the
ORG statement to make more memory available. You will
need to lower your CLEAR instruction also.

RAINBOW Info

How To Read Rainbow

Please note that all the BASIC
program listings you will find in the
Rainbow are formatted for a 32-
character screen — so they will show up
just as they do on your CoCo screen.
One easy way to check on the accuracy
of your typing is to compare what
character "goes under" what. If the
characters match — and your line
endings come out the same — you have
a pretty good way of knowing that your
typing is accurate.

We also have "key boxes" to show you
the minimum system a program needs.
But, do read the text before you start
typing.

Finally, the little cassette symbol on

CERTIFICATION
SEAt

The Rainbow Seal

The Rainbow Certification Seal is our
way of helping you, the consumer. The
purpose of the Seal is to certify to you
that any product which carries the Seal
has been physically seen by us and that
it does, indeed, exist.

Manufacturers of products —
hardware, software and firmware — are
encouraged by us to submit their
products to the Rainbow for
certification. We ascertain that their
products are, in actuality, what they
purport to be and, upon such
determination, award a Seal. This lets
you know that we have seen the product
and that it does, indeed, exist.

The Seal, however, is not a "guarantee
of satisfaction." The certification
process is different from the review
process. You are encouraged to read
our reviews to determine whether the
product is right for your needs.

There is absolutely no relationship
between advertising in the Rainbow and
the certification process. Certification is
open and available to any product
pertaining to CoCo. A Seal will be
awarded to any commercial product,
regardless of whether the firm
advertises or not.

We will appreciate knowing of
instances of violation of Seal use.

Using Machine Language

Machine Language programs are one
of the features of the Rainbow. There are
a number of ways to "get" these
programs into memory so that you can
operate them.

The easiest way is by using an Editor-
Assembler, a program you can purchase
from a number of sources.

An editor-assembler allows you to
enter mnemonics into your CoCo and
then have the editor-assembler
assemble them into specific instructions
that are understood by the 6809 chip
that controls your computer.

When you use an editor-assembler, all
you have to do, essentially, is copy the
relevant instructions from the Rainbow's
listing into CoCo.

Another method of getting an
assembly language listing into CoCo is
called "hand assembly." As the name
implies, you do the assembly by hand.
This can sometimes cause problems
when you have to set up an ORIGIN
statement or an EQUATE. In short, you
have to know something about
assembly to hand assemble some
programs.

Use the following program if you wish
to hand assemble machine language
listings:

10 CLEAR200,&H3F00:I=&H3F80

20 PRINT "ADDRESS:";HEX$(I);

30 INPUT "BYTE";B$

40 POKE l,VAL("&H"+BS)

50l=l+1:GOTO20

This program assumes you havea 16K
CoCo. If you have 32K, change the
&H3F00 in Line 10 to &H7F00.

What's A CoCo

CoCo is an affectionate name which
was first given to the TRS-80 Color
Computer by its many fans, users and
owners. As such, it is almost a generic
term for three computers, all of which
are very much alike.

When we use the term CoCo, we refer
to the TRS-80 Color Computer, the TDP
System-100 Computer and the Dragon-
32 Computer. It is easier than using the
three "given" names throughout the
Rainbow.

In most cases, when a specific
computer is mentioned, the application
is for that specific computer. However,
since the TDP System-100 and TRS-80
Color are, for all purposes, the same
computer in a different case, these terms
are almost always interchangable.

The Rainbow Check

The small boxes which you see with
programs in the Rainbow are our RAIN-
BOW CHECK program, which is
designed to help you type in programs
accurately.

The check program will count the
number of characters you type in. You
can then compare the number the
RAINBOW CHECK gives you to those
printed in the Rainbow. On longer pro-
grams, some benchmark lines are given.
When you reach the end of one of those
lines with your typing, simply check to
see if the numbers match.

To use the RAINBOW CHECK, type in
the program, CSAVE it for future use,
then type in the command RUN and
press ENTER. Once the program has
run, type NEW to remove it from that
area into which you will be keying
programs.

Now, whenever you press the down
arrow, CoCo will give you the hexade-
cimal number of bytes in memory. This
is to check against the numbers printed
in the Rainbow. If your number is differ-
ent, check the listing carefully to be sure
you typed in the proper BASIC program
code.

As the hexadecimal number appears
in the upper-left corner of the monitor
screen, you may want to clear the screen
and press the spacebar five or six times
to move the cursor out of the way for
easy reading. The RAINBOW CHECK
counts spaces, too, follow the spacing
just as it appears in the magazine.

Here's the program:

10CLS:IF PEEK(116) = 127 THEN
X=32688 ELSE X=1 6304
20 CLEAR 25.X-1

30 IF PEEK(116)=127 THEN X=32688

February 1984

Microcomputers are good for a lot of things that
used to be done by hand, like filing, counting,
simple arithmetic, typing complicated mathemat-
ics, or game playing. Only when computers began doing
things that couldn't be done any other way, were we in the
computer age. The first video game. Pong, was evolution-
ary. It had its alter ego on the tennis court because it could be
"played"there. But the computer game. Breakout was revo-
lutionary. It had no such alter ego in the real world. It only
made sense as a video game and was a true "computer"
game. Scientific programming had the same evolution.
Early computers could calculate the roots of a quadratic
equation very fast but there already was a simple equation
for it, so computers weren't needed. Image processing
needed a. compMcv . Stereo viewers and overlaying transpar-
encies were crude tools for image enhancement. The compu-
terand its lightning-fast speed revolutionized image process-
ing to create what it is today.

Image processing is seen all around us in magazine adver-
tisements, police fingerprint identification, the weather
report, medicine, and the entertainment industry (especially
television). The most dramatic examples have been the
phenomenal satellite pictures from Jupiter and Saturn. The
original "images" were just streams of zeroes and ones with
noise. These are smoothed, enhanced, averaged, and modi-
fied into the pictures that we see. Without digital image
processing, this science, and what it produces, would not be
possible.

What is image processing? It is the procedure where a
two-dimensional image is changed to make it more easily
perceived, by either the human eye or an electronic eye. The
useful information is contained in a raw image, but it is often
obscured by blurring, camera or object motion, electronic
noise, or background light. Image processing can be applied
to remove the obscuring effects and retrieve the information.

What does the program do? Lines 500-510 contain the
menu and "traffic cop." Everything branches from here.
Lines 9000 — 9026 contain a coded "image" of the planet
Saturn to use as an example. The image is coded as strings of
hexadecimal values with G=I6 rather than 10. The rest of
the program works in an "operator" fashion. That is, a
section is branched to. something happens, and it returns to
line 500. What happens? Now the fun part comes in.

Listing I is a BASIC program that demonstrates the impor-
tant techniques and allows you to enhance any image. The
program also shows the versatility of the TRS-80 Color
Computer for serious scientific work. It requires a 32K
Extended BASIC CoCo (with disk and printer optional, but
recommended). The program proceeds by allowing you, the
user, to "operate" on a Raw Image and then display the
Processed Image. You can use this process to "operate"
again and again, and produce more processed images. You
should remember that the processing is usually irreversable
(called Destructive) and "inverse" operations are rare. In
other words, once you smooth a raw image you cannnot get
the raw image back unless you stored it somewhere. This
makes a disk drive useful and almost necessary. You can
store and retrieve images quickly. For those without a disk, I
will describe the modifications you need for cassette tape
storage.

The program is menu-oriented. After keying-in the pro-
gram, type RUN. Remember to leave spaces as you type
since the compressed format will only work after it is token-
ized. The logo will be displayed while it loads a machine
language program from DATA lines 9100-9106. A menu
will appear with eight choices. Three of the options will not

alter the image (D.V.P); five of them will change it. I will
briefly describe how the program works and then tell you
how you can use it.

Memory area S4A00— S4C0B contains a machine lan-
guage program shown in listing 2. This accomplished all the
tough tasks fast. I originally wrote the whole program in
BASIC but it wasjust too slow. It took three minutes just to
display the image with G£7"and PUT. Memory area 23072
— 26143 contain the image. It is a 64-column by 48 row
matrix with 64 gray levels. It contains 64x48=3072 bytes.
Memory are 20000—23071 contains a scratch pad area.
Whenever a complicated operation is performed, the com-
puter must "read" the image and store a result without
altering the original image. Only when the process is com-
plete does it transfer the scratch pad over to the image
matrix for you to see. The memory area above 26144 is
available for a printer driver routine for graphics hard copy.
My program loads the routine from line 2264. Your routine
should load it there too. Just change DEFUSR7 in line 23 to
whatever address your printer driver needs. Also set the
POKE 150 in line 2264 to the Baud rate of your printer/ in-
terface. If you use a 600 Baud printer (like DMP 100. DMP
200. LP VII, etc.) don't POKE anything.

Lines 1000 — 1330 create an image from a menu. Four
images can be formed. The first is a test pattern which has all
the gray scales (density of dots) and the letter "H." The
second is an image of the planet Saturn (only the non-zero
lines are stored indata; the zeroes are entered by clearing the
image witha USRI call in line 1200). The third possibility is
loading a previously stored image. The program is set up for
disk storage, but a simple CLOADM K$ in line 1320 will
allow tape storage. Also change line 8020 to read CSA VEM.
etc. if you are going to use cassette tape. The fourth "image"
is choice — just clear the image.

Lines 2000—2264 display the image on the screen in 64 x
48 picture elements (pixels) with from to 1 6 dots in a pixel.
This means it is actually 1 7 gray levels but no image process-
ing scientist would admit to having an odd number of gray
levels. The display routine is in machine language located at
S4AF2. It steps through the rows and columns using the
value of the pixel to offset a lookup to the table of dot-
pattern values stored at$4BC7. It then moves the dots to the
most-significant nibble (4 bits) or the least significant nibble
of the 8-bit "word." It stores this value on graphics Page I. If
you press [H] while the display is on, the program jumps to
your printer driver routine to produce a hard copy for you.
Any other key-press will just return you to the menu.

Line 3000 performs an "edge enhancement." This is a
Destructive operation which will highlight all the high con-
trast edges in your image. Low contrast areas like smooth
surfaces will just be zeroed. Sharp edges are enhanced. The
ML routine at S4A98 performs this operation. It steps
through the rows and columns and subtracts neighboring
values to the right and below it. It then takes the absolute
value of this sum and stores it in the scratch pad. Alter all the
pixels (except the border which doesn't have meaningful
neighbors) are operated upon, the routine transfers the
scratch pad into the new image.

Lines 4000 — 4040 add noise to the image. This is done in
BASIC with the RND function. Adding noise is not image
processing, but it is necessary to show you what a processor
can do witha messy image. This routine is here just to "mess
up" your image so the real image processing can be demon-
strated. It is, by definition, Destructive. You arc prompted
for the number of pixels you want noisy. A "little" noise may
be 100 pixels and a "lot" of noise is all 3072 pixels. The value

February 1984 the RAINBOW 197

of the noise is the seed of RND for adding it to each pixel.
Any number will do to simulate real image noise but I like 5
just to make it look neat.

Lines 5000 — 5600 display the image in pseudo-colors.
This is a Non-Destructive process which just displays the
image on a PMODE I screen in four colors. Low valued
pixels are green, next are yellow, etc. This is called pseudo-
color, since it is often used to outline certain regions in an
image when the image itself (like a medical X-ray) has no
color information. After all. Saturn is really not green, blue,
red. and yellow in the way that you will see it here. This
routine is slow since it is written in BASIC. 1 didn't write it in
asssembler since 1 use it very little. The four gray levels (four
colors) are good for CoCo demonstrations, but not for
serious work.

Lines 6000— 60 10 perform a nine-point smoothing opera-
tion. This is a Destructive routine in ML at S4A30. This
routine steps through the rows and columns and takes the
average value of the pixel and it's-eight surrounding neigh-
bors. It puts it in the scratch pad and then, when it completes
all the pixels, it transfers the scratch pad to the image.

Lines 7000 — 7570 allow a histogram modification. The
histogram is essentially a table of conversion values for the
display. Normally when the value of a pixel is 5 it will display
five dots in that pixel area, or 1 1 dots for a value of 1 1 , etc.
however, by modifying the histogram, we can make the
image scale change. As an example, if you have a constant
low light level background in an image with a value of three,
the image tends to "wash out" . . . like watching a movie
with the house lights on. If we subtract three from each
pixel, the final image would have the "washout" removed.
The routine in BASIC and ML at S4B97 allows you to thresh-
old, add or subtract a constant value, or make a custom
histogram. The custom histogram is most useful for elimi-
nating weird camera effects or blurring. In all cases, the new
histogram, ie, the conversion, will be displayed before you
commit, since this is a Destructive process. You can't be too
careful.

Lines 8000 — 8030 save the image in memory 23072 —
26144 to disk. Tape cassette modifications are described
above.

Sinceyou're now probably tired of readingall of this, let's
go through an example to see just what this image process-
ing is all about. Load the program and type RUN. The ML
program will take a few seconds to load. At the menu hit [C]
to create an image. At the "create" menu, hit [2] [ENTER] to
produce the image of Saturn. It will take about a minute to
read the data. The main menu will appear. Now hit [D] to
display it. Wow! The image should look like figure I. If you
want a hard copy (ie, your printer is on, and you changed
lines 23 and 2264) then hit [H] otherwise, hit any key and the
main menu will reappear. You can always redisplay it any
time.

Now, let's see what the program can really do. Hit [N] For
noise. At the prompt for the number of pixels, type 1200
[ENTER]. At the prompt for the strength, type 5 [ENTER].
Watch the counter as it fills in random pixels. Now from the
main menu, hit [D] and look at that mess! Your image
should look like the noisy image in figure 2. The multiple
reproductions necessary to print images in magazines have a
"smoothing" effect so your image should appear noisier
than that shown. This problem consistently causes magazine
and newspaper publishers fits. But here's what can be done
about it. Go to the main menu with your noisy image of
Saturn. Hit [H] for histogram modification. Now hit [A] for
add and type -5 [ENTER]. This will subtract five from each

pixel. Now [D], display the image; it should look like figure
3. Not bad, but let's go further. From the main menu hit [S]
to smooth the image. Now display it. Figure 4? That's a good
image, but we can do better. There were too few bright areas.
In other words, the contrast was low. From the main menu
hit [H] to modify the histogram again. Let's just multiply
each value by two to double the contrast. How? Use the
custom histogram; hit [C]. Now just type in the following
custom histogram:

-> 0, I -> 2, 2 -> 4, 3 -> 6, 4 -> 8, 5 -> 10, 6 -> 12,
7 -> 14. 8 -> 16, and all the rest -> 16.

When it asks "Sure?"check your input and type [Y], Now
look at your restored image of Saturn, figure 5. Not exactly
like Figure I, but that is not mathematically possible after
you inserted random noise. It's still a pretty good attempt at
it.

The rest is up to you. Try the test pattern and hit [E] to
edge enhance it. Or smooth it. Or use the data lines to enter
your own image. As demonstrated, the possibilities are
endless.

This article gives you an introduction to the science of
image processing. By no means is it complete. There are
many other methods employed. Something called "filtering"
is a very powerful tool. Smoothing and edge enhancement
are special types of filtering and there are volumes written on
the particular topic. If you're interested, keep at it. Try your
own combinations and see what you can do. The computer
age is here for all of us. Rainbow Check

CAPTAIN EIGHTY

Adventuring
With
Style

By Bob Liddil
Be cautious, and remember . . . the word is everything.

Here's Joe Adventure, preparing for another all
night session at the keyboard. We go down the
checklist, point by point, making sure that nothing
is left out.

Coffee, ten gallons. Check. Sunglasses to protect eyes
from screen glare. Check. Phone off hook. Check. Wife and
kids on bus to Toledo. Check. Shades pulled, dictionary and
thesaurus nearby. Check. One copy of Attack Of The Killer
Dragon That Ate New Jersey. CoCo version. Check.

Right! Now we begin.

As Joe plunges forward in this, his 1 7th attempt to solve
this computerized version of kill the customer by driving
him insane, we shall examine the wonderous compu-
phcnomona known as Adventure. Note the capital A which
is accorded the genre by true affectionados.)

As long as there has been man there has been Adventure.
Oog, prehistoric cave guy, first discovered this unique expe-
rience when he whacked a Tyrannosaur with a tree limb and
then tried to run into a cave. Unfortunately, GO CAVE was
executed before MOVE BOULDER and poor Oog became
the first dinosaur TV dinner.

All through history, man has been locked in blind pursuit
of elusive Adventure. The books are filled with examples of
brave heroes who entered the wrong commands. There was
Captain Vladimir Vaselescov, for example, whose burning
desire to become the first Russian to reach the North Pole by
sailingsoulh caused him to EXAMINE PENGUIN without
WEARing GLOVES. Vaselescov became the first explorer
ever to die in a penguin stampede. If he'd seen the ribbon she
was wearing, he would have realized she was the only female
penguin in the entire Antartic, thus avoiding an unnecessary
stomping.

( Bob liddil, Captain Eighty, is a well-known writer on
Color Computer topics who has numerous columns
and several hooks to his credit.)

Computer art imitates life. While the picturized Adven-
tures dilute the impact of different interpretations of the
same phrase, the true text Adventure leaves everything to
the imagination. In Adventure, the word is everything.

A simple statement: YOU SEE — HAND GRENADE,
PEN. BOX becomes a nightmare of possibilities. The verb-
noun combinations which make up the command structure
and allow interaction with the program can be manipulated
by the author with ease.

EXAMINE. Okay, do that to the grenade. Computer
says, YOU CANT DO THAT . . . YET. Curses! You are
committed. GET HAND GRENADE. Computer says OK.
EXAMINE it now? Computer says it is ticking. Well, there's
a pen, but it's spelled wrong so it may not fit. Typing HELP
may or may not render assistance. If you DROP it you may
get blown up. BetterTHROW GRENADE. Computersavs
GRENADE EXPLODES. We anticipated that. LANDS
IN PEN AND EXPLODES says the computer. IN the
PEN? PEN turns out to be PIG PEN and now there is
enough bacon to last your whole journey. All you need is
eggs and juice and you'll satisfy government requirements
for a balanced Adventure.

As every Adventurer discovers, the author is in the full
control of the scenario at all times. In order to solve the
puzzle the user must be prepared to think like the author.
Indeed, he must BECOME the author as he works his way
into the depths of the game.

Different authors approach Adventure in different ways.
There is the hardnose, or high tech. style. In Sands of Egypt.
we have an author engaged in the grim business of totally
stumping the player. This game plays like shooting BB rifles
on the midway at a county fair; very few hits and a nearly
unattainable goal. This style is a play for the ride. Winning is
a brass ring. The high tech style is most suitable for the very
smart, the very patient, and the emotionally stable Adven-
turer, or for somone with a fully insured computer.

The classic style is easier to swallow.
A classic is usually goal oriented with
pieces of the puzzle scattered about and
fitting neatly together to form a solu-
tion. The text Adventure Dragonquest
occupies this opposite end of the scale
from the frustration (challenge) of high
lech. Users can easily tune in the young
Charles Forsythe as he guides them
through Lower Graylockland in search
of Smaegor the Princess Snatcher. He
has provided tools for the win. without
denying all but the most clever access.
Instead, he makes the overall problem,
rescuing the princess, the most difficult.
The tools needed are sub-puzzles simply
solved. There arc a few tense moments
at the beginning when the King refuses
to allow the player to leave the castle.
But the keywords can be worked out
without the help of a Harvard profes-
sor. By the way. what is a MANATEE?
And would you go swimming in the
same river with one?

The flip style or the irreverent style, if
you prefer, employs elements of the
other two. Gamster Software's Madame
Rosa's Massage Parlor, which is about
as naughty as a bikini calendar, pro-
vides endless word twists and blind
alleys caused by letting the imagination
run wild. But, at the same time, it is very
classic in its goal orientation. Madame
is tough, but not unwinnable. More
importantly, it is I6K of belly laughs.
Author Bob Krotts pokes fun at the
whole Adventure genre and gives the
player something to do other than slay
dragons or escape deadly traps.

Each of the three styles mentioned
makes specific demands on the audience.
High tech requires literal interpretation
and cunning logic, an almost telepathic
draw on the author's intent. Classic is
more story oriented with goals plainly
defined. Flip plays to the sense of humor
and the user's willingness to be manipu-
lated ot led astray in the name of
comedy. The later two can be won with
effort and patience. The first requires an
iron will, a master's in parapsychology
and a loving, understanding family. A
strong local mental health office should
be a consideration also.

There are roughly 10 Adventure titles
for every "Twitch" (arcade game). This
is attributable in part to the ease of cod-
ing and divergence of thematic possibil-
ities, versus the logistics of animation.
Not all of these make it to market. There
can be found on BBS's and in private
uploading clubs tens of hundreds of
Adventure programs placed in the pub-
lic domain by first authors anxious for
approval from their peers.

Commercially, the variety is over-
whelming. Calixlo Island from Mark
Data shares the line with several highly
animated and well-planned programs.
Prickly-Pear's Adventure in Wonder-
land employs the still experimental sen-
tence-style command mode and explores
a very popular classic children's story.
Sands of Egypt, Black Sanctum, Drag-
onquest, Beyond the Cimeeon Moon,
the list reads on and on, like the titles in
a fiction library, each trying to outdo
the other in cleverness and plot.

Beyond all this, whether the program
is illustrated or pure text, you will find
the written word. The bottom line in
Adventure is reading comprehension. I
believe, based on this fact alone, that
Adventure is the ideal computer game
for kids (and adult alike). Even with all
the motor skills that are developed with

the Twitch, there can be no more valua-
ble exercise to anyone than reading. For
the micro-computerist gamester, there
can be no challenge greater than that of
one mind pitted aganst another; no
teamwork more satisfying than friends,
as a group, solving a killer puzzle.

And what of Joe Adventure?

It's five o'clock in the morning. Joe
has to go to work at nine. He's taken the
sword from the stone. He knows where
the dragon is hiding. He's even made it
through the dark woods. Butthe HELP
command's been giving conflicting an-
swers all night. The coffee's cold, he's
been in the river twice and a question
burns in the gray of the pre-dawn.

"Pray tell me. Sir Author." he la-
ments, "what DOST thou feed to a
MANATEE?" _

REVIEWS

TALKING SPELLER

Editor:

I must reply 10 H. A. Manning's response
(November, p. 237) to my review of "Talking
Speller" (September, p. 199).

Marshall McLuhan warned that we must
avoid approaching new media and technol-
ogies "through a rear view mirror," pouring
the obsolete content of the old into the new,
ignoring the potential of the new for original
ideas and messages. The "rear view mirror"
phenomenon is taking place in a great many
educational programs written for the Color
Computer.

Research in the learning of spelling shows
that even youngest children, drill in words
taken out of context does not produce lan-
guage mastery with much efficiency. This is
not a matter of "philosophizing," as Man-
ning phrases it, but of fact. A computer pro-
gram that merely replaces a teacher but still
teaches rote mastery of spellings is. there-
fore, suspect on very real pedagogical
grounds. I believe it is the duty of the
reviewer to point out pedagogical weak-
nesses in educational programs written for
the Color Computer. It is not enough merely
to plug in the program and to attest that it
runs smoothly. A badly conceived program
must be identified as such, even if it runs to
perfection.

As an educator. I am concerned first with
the quality and secondarily with seeing home
computers can move education forward. As
a reviewer — for Rainbow or any other
magazine — I will continue to point out
misuses of computer technology when 1 per-
ceive them.

Stephen N. Tchudi
Okemos, Ml

am disappointed to see that a reviewer with
the responsibility of thoroughly investigat-
ing a product for your readers would not
even contact the manufacturer concerning
the attitude of this reviewer and rely on the
reputation lor quality that the Computer-
ware label represents.

BIO DETECTOR

Editor:

I would like to respond to Rainbow's
review of Computerware 's Bio Detector.
First, it is not a game! The Bio Detector's
primary purpose is for biofeedback using
galvanic skin response. We have several
institutional customers using their CoCo
and Bio Detectors in special biofeedback
programs. A game program called Anxiety
Attack is included for fun and reportedly has
been a big hit at many parties.

Secondly, the Bio Detector does work'.
The most common comment we have re-
ceived from customers is how sensitive it is!
Of the many hundreds of Bio Detectors sold,
we have not received a single one returned. I

LOWRCASE

Editor:

Here is a review of Ed Lowe's review of the
Lowrcase descenders program for the
Radio Shack DMP 100 printer (from KRT
Software). He obviously expected some crit-
icism, having so stated in his review. Here it
is: If a review on any product is to be pub-
lished, there is a responsibility to readers to
be objective and thorough.

If the reviewer had tried Lowrcase with
Telewriter 64 he might have been quite
pleased with the results. The DMP 100.
Lowrcase, and Telewriter 64 are used in my
business (writing and formatting resumes).
When my typesetter complained about the
lack of descenders on resume draft layouts, I
ordered the Lowrcase from KRT. Frankly,
the first two tapes failed but KRT not
only stood behind its product, they sent me
the llight simulator program to compensate
for my troubles — and. by the way. that
program is fantastic!

The descenders program works extremely
well and, contrary to popular belief, does
work at the 1200 Baud rate. There is not an
objectionable printing slow-down (as com-
pared to printing time without the descend-
ers program). Finally, the results are infi-
nitely belter than not having descenders
print. I am no longer ashamed to use the
DMP 100 lor correspondence purposes!

Is the descenders program worth it? Lowe
says not. I say. from the perspective of a
businessman, it most assuredly is; SI 5.95 is
considerably less expensive than buying
another printer with built-in descenders!
Shame on you for printing an incomplete
review. I trust future reviewers will be more
thorough in trying and reviewing products.

Editor:

I would like to comment on a review made
by Ed Lowe in the December 1983 issue
about KRT Software's Lowrcase Descend-
ers program. 1 had purchased that program
myself for my LP-VI1 (now sold) and was

very pleased with it, although it was rather
expensive. What exactly did he expect for
S 1 5.95, a hardware mod? It, by the way, does
not double space but rather gives a sort of
I '/$ spacing which I find better than the orig-
inal. The program thus gives 49 lines per
page instead of 66. I agree it was slow, but
what did he want?

Paul Gani
Marshfield. WI

Editor

Boo. hiss, on Mr. Ed Lowe's review of the
Lowrcase program. The review is located on
Page 262 of the December, 1983 Rainbow.

1 have been using the package almost daily
since it was sent to me July 22, 1983. 1 am
very pleased with the results. 1 use it in con-
junction with a Telewriter-64 program for
output on a DMP- 1 00 printer. As stated by
M r. Lowe, "it was the most 1 could afford
The Lowrcase program has allowed my
DMP-100 to move into the word processing
world "of the 'bigger' dot-matrix printers
with true descenders," as a result of the new
character set style afforded by this program.

At the church, I use the system weekly to
send out letters to visitors and 1 also use it to
support various organizations in the church
with "form letters." There have been no
complaints! To date that includes both the
editor and my son's test grades.

Granted, what Mr. Lowe indicates about
throughput is indeed true. It docs require
almost twice the time to print a line, since
two passes are required. The vertical spacing
is not quite double, however. My 11-inch
form under Telewriter-64 now has 49 lines
instead of 66. In addition, there is a little
more vertical spacing on my program print-
outs which really improves their readability.

Not only do 1 feci the package is well
worth the $15.95 price, compared to the cost
of real descenders on a matrix printer, but I
have never, never had it cause any system
problems, nor produce unexpected results.
That's high reliablity.

Now that I've said the above I feel that I
must editorialize just a bit. Mr. Lowe's
review and my rebuttal simply illustrate a
very salient point in the software world: the
ability of a software offering to perform the
task which the purchaser wishes to perform,
at a price he wishes to pay to have the job
done. Those who achieve the desired results
arc happy. Those who feel the offering does
not meet their expectations arc unhappy.
The key word here is the word "expecta-
tions." Unclear advertising, half-truths, and
sales "hype" all contribute to establishing
the expectations for a software offering.

212

the RAINBOW February 1984

Sometimes [he expectation is extremely
false. The real caveat becomes "try it. you'll
like it" ... or maybe you won't! But you'll
probably have to try it to be sure.

One other quick note. On two occasions 1
have had the privilege to discuss program
problems with the proprietor of KRT Soft-
ware. Mr. Ken Elder. The first occasion was
a result of changes made in Telewriler-64.
The second was concerning his program and
a spooling application. This brings up the
subject of "support" after purchase. Let me
just say that, in both conversations with Mr.
Elder, I found him to be honestly interested
in my problem and eager to assist me in
developinga solution. With individuals such
as him writing and selling (and servicing)
software the marketplace will never be
"caveat emptor."

Keep up the fine magazine. It's the best
CoCo magazine on the shelf! Please include
more OS-9 information for those of us who
have purchased this fine operating system
from Radio Shack.

Editor:

While I hold no special interest in KRT
Software, or in the Lowrcase program, the
review was somewhat disturbing to me.

The reviewer made a statement that he did
not even try the program with the Cognitec
Tclcwritcr-64 text processing program. To
anyone who has used the Lowrcase pro-
gram, it is obvious that Lowrcase was writ-
ten principally for that purpose. Thus, the
reviewer in his lackadaisical approach seems
to have completely missed the major point.

What disturbs me is this: is this the normal
method used in reviewing products for your
magazine? Is it usual for a reviewer to do
only part of the job of testing a product'.' If
so. then you are doing a poor service for
your readers. Better no review at all than a
job only partly done.

My immediate reaction to this particular
review is that I am now somewhat distrustful
of all the product reviews which you print.

Editor:

I just finished reading the December
review of K RT Sol'twa re's program Lowrcase.
and was immediately prompted to write you.
Having recently received my copy of Lowr-
case. I could not believe what my eyes were
reading in the Rainbow:

At least the reviewer was honest enough to
admit that he never used the program with
Tclewriler-64, I am bothered, however, by
someone who would pan the work of another
in a major publication without doing his

homework, and then have the nerve to admit
it. Not only am 1 pleased with the KRT
product, as you can tell from the print
obtained with my DMP-100. but I would
also like to add a word of praise for the
people at KRT as represented by Mr. Ken
Elder. I have found Mr. Elder to be a very
helpful and concerned individual who will
cheerfully spend time with his customers to
assist them in their use of a software product
new to them.

As always, three cheers for the Rainbow,
the magazine for the Color Computer.

CC-DBM/LW

Editor:

The December issue of Rainbow carried a
review of CC-DBM/LW on Page 268 by
Gerry Schcchter. I read this review as part of
reading your great magazine from cover to
cover as I always do.

Based on the review and my need for an
easy way to crank out a short letter to one
person or a group, 1 decided to purchase this
software from EVS Engineering.

In the EVS Engineering ad on Page 9 it
says "Personal checks — OK wc won't make
you wait." Let me tell you what that means.
On November 2 1 1 sent EVS a discount cou-
pon and a personal check for $.11.95 (in-
cludes $2 for shipping and handling). The
EVS invoice indicates they processed the
order on November 23. and sent the soft-
ware to me on the same day priority mail at a
cost of $2.58. I had the software on Novem-
ber 26. Who can ask for more than that for
service?

Now. about this EVS software that I pur-
chased. Gerry Schecter's review is very accu-
rate. "If you arc in the market for a full-
blown database or word processing system,
then you should look elsewhere." I know this
to be true because, based on another Rain-
bow review. 1 purchased Telewriter-64 some
time ago. Now. CC-DBM/ LW is not Tele-
writer-64. but. it is just as great in its own
way.

To sum it ail up. good review, good soft-
ware, good value and as usual, good Rain-
bow. By the way, this letter was done using
EVS Engineering's CC-DBM I L ^'software.

SONAR SEARCH

Editor:

I am an author for Shell Software, and I
wrote the program Sonar Search which was

reviewed in the November 1983 issue of your
magazine. I was pretty satisfied with the
review except for one thing. The reviewer
stated that he got a very negative reaction to
the price of $ 1 8.95 for a program written in
BASIC. In my opinion, that is simply absurd!
First of all. would rewriting the game in
machine language justify the price? Remem-
ber, as staled in the review. Sonar Search is
not a high speed shoot-em-up. and it wasn't
meant to be. therefore machine language
wasn't needed. Secondly. $ 18.95 is not a high
price to pay for a game since many games
cost $25 to $35. 1 can sec charging a Utile
more for a machine language game over a
basic game, since a machine language game
usually takes longer to wrile. bul not as
much more as is implied in the review. Oth-
erwise. 1 feel it's like paying an employee
more or less than another employee on the
basis of race or sex. As long as the employee
does a good job. who cares about the race or
sex of the employee? Likewise, as longas the
game is good, who cares about the language
the game is written in? In fact, when 1 sec a
game advertised for a very low price. I begin
to wonder why it costs so little.

The reviewer seemed to think that the
packaging was the culprit for the "high"
price. Well, lei me tell you that after the price
of the cassettes, printing of the instructions,
artwork, and all of the time thai goes into
writing the program are considered, the
price of the packaging has very little effect
on the price of the game. In fact, all games
from Shell Software are packaged like Sonar
Search because we got a low price on a large
quantity of the packages.

Since I am on the subject of reviews, let me
tell you about an idea that 1 have for review-
ing programs. You see. your magazine is the
largest magazine dedicated to the CoCo.
Therefore, the opinion of one reviewer on
your staff will probably determine, to a large
extent, whether the program reviewed will
sell or not. 1 do not consider this a fair sys-
tem because opinions can vary greatly from
one person to another. An example of ihis
goes back to the packaging of our programs.
The revjewer of Sonar Search didn't seem to
like our packaging much, but the reviewer of
Death Star (also by Shell Software, re-
viewed in the April 1983 issue of the Rain-
how) was impressed with it. This is actually a
trivial matter since it has nothing to do with
the game itself, but it illustrates a difference
of opinion. Since opinions can vary so
much. I feel thai two people should review
each program, possibly with opposing views
so each reviewer could point out what they
did or did not like about the program. Oth-
erwise. I feel you have a great magazine.

Valhalla — A Very Good
War Game For The CoCo

By Tom Roginski

I have played all types of war games starling with the old
board game "Gettysburg" and continuing to the modern
computer war games of the present. The Apple and the Atari
have had true war games for some time; the CoCo only
recently. I 'alhalla is a fine recent entry which does qualify as
a true war game. It also has the addition of some fine
graphics. As with all such games, the rules arc not simple. I
will present the basic flavor of the game without giving
complete details.

Valhalla is a board game played between two teams with
the computer acting as the scorekecper, map maker, and
judge. This approach makes for a much faster game than
similar games do without the computer. More moves can be
made in a given period of time and no time is lost with
disputes between players. Each team consists of one or two
players who are in command of various armies and officers.
Each team starts with two lords, two generals, four captains,

and eight armies consisting of five swordsmen, five archers,
five light cavalry, and five heavy cavalry units each.

While each team starts out even, the way the forces are
used determines the final outcome of the war. These forces
must be moved around the field where various castles, vil-
lages, mountains, marches, rivers, and river fords are
placed. Castles must be used for defense and to gain
replacements for forces lost in battle. Villages must be used
for supplies. You start out with five turns of supplies and
must pass through a village to obtain more supplies or you
will suffer a loss of men. The only way to make an aggressive
attack into enemy territory is to either stock up on supplies
or to capture an enemy city.

The strength of each type of unit in combat is determined
by the unit's basic strength modified by several factors. The
strongest basic unit is the heavy cavalry and the weakest are
the swordsmen and archers. Basic fighting factors of the
units arc modified depending on terrain. Heavy cavalry has
its basic strength increased in the open or on a road while it is
decreased in a ford or other bad ground. In the rough, light
cavalry is actually better than heavy. The designers of this
game have done a good job researching the tactics of land
warfare. By careful use of the terrain, a weaker unit can
defeat an otherwise more powerful one.

There are two basic types of graphic screens used in this
game. The usual screen is the map. This screen is an excel-
lent, Hi-Res picture of the battlefield. On this screen the
terrain, villages, and castles are shown. Included with this
game are two different map setups or scenarios. More scenar-
ios arc promised in the instruction sheet. Scenario One is
rather even with the two sides of the board almost, but not
quite, mirror images. Most of the play between evenly
matched players might be made in this scenario.

Scenario Two has the two sides of the board rather differ-
ent. The blue side (which moves first) has a terrain greatly
cluttered with rough ground, marshes, and other movement
problems. This works to the disadvantage of the blue player
giving him or her problems in moving. One portion of the
force located behind the lake is especially difficult to move
into action. The terrain also works to some advantage of the
blue player by making it difficult for the red player to get
around the board to attack. If the players are greatly differ-
ent in playing ability, giving the weaker the red side in this
scenario will give him a chance to get used to the game and lo
set up a defense.

The other type of screen used in this game will lead me to
describe what is probably the game's only flaw. A battle
begins after any movement phase in which two opposing
armies are moved in contact with each other. The two sides
are then represented as four Hi-Res symbols for each of the
four types of military forces (swordsmen, light cavalry,
heavy cavalry, and archers). A number is then placed along
the symbol to indicate the number of this force remaining in
the army. The attacking player and then the defender each
place six units on the front line. The officer of each side is
then placed. At this time, the computer puts these symbols in
the proper position and starts the generation of random
numbers.

Each unit is played against the unit in front of it. After
each unit is played the loser is removed from the board and
the players arc asked if they want to retreat. If a side wishes
to retreat, it may do so automatically and without additional
losses. It may be only my opinion, but I do not agree that no
retreating forces should be lost. Because of the lack of

214

Ihe RAINBOW February 1984

communication in medieval and ancient warfare, major
losses can occur during a retreat.

It is when more than two opposing armies are in contact
that the game shows its only flaw. The battle board only has
the ability to show one army against another and each unit
against only the unit placed in front of it. When the attacker
or the defender have more than one army, the other force is
not used in the first battle. All battles are one army against
another. The additional force must fight after one of the first
two armies have been eliminated or retreats. If one player
has only two units left and cannot retreat, his two units do
not have to fight more than the two units directly in front of
them. In the history of war. the principle of bringing all
possible force to bear against a single point is of prime
importance. This principle must be employed here by using
the terrain factors to advantage. A force cannot retreat with
a riveror lake behind it. You can attack with one unit until it
is reduced to a certain level, retreat it. and then attack with
the second unit.

One additional refinement should be mentioned. If an
army is in a castle, it has the choice of coming out of the
castle lo auack or to stay in and accept a siege. If I he-
defender stays in the castle, the attacker can try to ram to
force a battle. If the ram fails, both sides lose a small number
of units and the attack stops. During the siege, the force in
the castle is not reinforced or resupplied. This siege feature is
a nice refinement.

A point system is used for the determination of the victor.
Each player starts with 200 points and then gets more points
for the destruction of enemy units and loses points for the
loss ol officers, castles, and villages. At the beginning of the
game the players decide how many turns the game will have.
A short game usually would result in an attempt to destroy
as much of the opposing force as possible while a longer
game will include the consideration of supplies and rein-
forcement.

Incomplete games can be saved to tape. This is done by
pushing the right joystick button instead of the left joystick
button when the scorecard is shown. Use caution when the
score shows because if you push the wrong button (which I
did several times) the computer will attempt to save instead
of going to the next turn. I have found that if the game stops
after an accidental attempt to save, it is usually possible to
get back to the game without any changes by typing:
GOT03 [ENTER]. This might be interesting if you wish to
try two different ways of completing a game from a specific
position.

The instruction sheet that comes with the game is ade-
quate. It gives a good, clear description of the game and the
rules. Its appearance is not the best, being a copy of a Line
Printer VII printout.

This is a very good game. Although the way the battles are
decided between unequal forces is not as I would like, this is
one of the best war games that is available for the Color
Computer. It is also one that would be considered a very
good war game and graphic display for any computer. The
minor exceptions that I have taken with the game are
probably partly due to the length of the game. There is no
room for the disk system. With the disk removed. I typed

Dyterm Is A Good Program
With Tough Documentation

The material says you can convert your CoCo into a
"smart terminal" inexpensively using Dyterm, While that is
so, they ought also to have another program to create a
"smart terminal operator."

Dyterm works, it is user modifiable, you don't have to
have Extended BASIC, and it does most of what is says it will,
but you have to be sharp to find out how and why. If you
know nothing about terminal programs, the documentation
lor Dyterm may leave you that way. The four-page docu-
ment often opens interesting questions, but does not give
what 1 call adequate directions.

As an instance, the neophyte may not quite understand
the designation of a data block as outlined in the documen-
tation. It would take only a few more words to clear up this
matter. An attempt is made on Page 4 of the document, but I
think it needs to be more specific.

There is a need to prepare cables if you arc using the
program between terminals. There is a description of these
in the documentation, but nary a hint if you can purchase a
ready-made cable or how to go about making one. I am
saying it is a good idea to be more specific about terminals
and terminal programs.

l think sometimes software authors just automatically
think everybody knows everything about computers. It
would be nice if they were right, but more and more people
are button pushers, and you have to think of them.

None of this will detract from the fact the program does
convert your CoCo into a terminal and will change Baud
rates (300 lo 2400) and stop bits and all the goodies.

It loaded right up from the tape and ran like a bandit in
the tape mode. After PCLEAR2ing, the tape was excellent
quality with no problems. Just lo make sure. I loaded a
version onto disk using the tape to disk program from Tom
Mix. which has been my good right arm.

Since Dyterm is a BASIC program with machine language
routines generated by BASIC, there is no problem of a start,
end or transfer address. It loaded to disk just fine and runs
like a bandito. (That is. quicker than tape!) The program
will drive my Radio Shack Modem II. and I was able to raise
Bob Rosen's B.B.S.

You have to toggle between send and receive by hitting the
[SHIF1 ] and the down arrow. I got that all mixed up and
only got as far as where Bob asked me my first name before I
blew the transmission out the window. It was my fault, but l
am like many other first users.

When I was cranking the program up. I called Bill Chap-
pie of Dynamic Electronics to discuss the program and ask
what he thought it was all about. He is a personable guy and
ready to answer your questions and learn from what you
have to say.

The text entering capability and preloading are a real plus
on this program. There is no provision for storing the text
from the buffer, but you should be able to remedy that
matter since the program is in basic and you could fit the
routine in if you wish.

There are many merits to this program, not the least of
which is low cost. I have a couple of terminal programs
which arc easier to run. but then again. I laid out quite a few
more beans to purchase them.

Dyterm also comes in cartridge form, which I did not
operate. The tape disk version is SI4.95 and the cartridge
sells for S24.95.

A serious programmer who knows what is happening will
like this program. Someone new to the computer world
might need some help.

Ice Master: A Refreshing
Change Of Pace

Ice Master, by Arcade Animations, Inc., is a simple bul
colorful game with good graphics and sound. In Ice Master,
the player does not assume any fantasy role identity such as
commander of an inter-galactic spaceship. It's you against
an assortment of computer-generated menaces in a fast-mov-
ing battle to destroy or be destroyed. Your only enemies are
mosquitoes and your only weapons are blocks of ice.

You begin the game surrounded by a number of mos-
quitoes, depending on the level of difficulty you choose.
These disease carrying insects swarm the screen, melting
your only defense device — the blocks of ice, while they seek
to extract your blood to destroy you. You are a little man in
the opening screen, hiding in a center safety box, patiently
waiting for a clear way out. There are approximately 50
randomly arranged blocks of ice surrounding you. Your
only objective: To survive by sliding the blocks of ice into the
mosquitoes and avoid getting stung.

The object of the game sounds simple. However, the
mosquitoes move at an extremely quick pace. You control
movement of your man with the right joystick and move the
blocks of ice by pressing the fire button which pushes the

blocks into the mosquitoes. There is also a bonus timer at
the top of the screen. The timer starts at 7,500 points and
decreases in increments of about 100 points per second.
Therefore, you have approximately 75 seconds to crush all
of the mosquitoes on the screen to obtain any bonus points.

Points are obtained by either crushing a mosquito (100
points) or by melting blocks of ice (25 points). Blocks of ice
can only slide one at a time and will melt if pushed when
another block of ice is adjoining. The faster you destroy all
of the mosquitoes on the screen, the higher your bonus
score. After completing a screen, you simply start the screen
over, with the only difference being a different arrangement
of blocks of ice.

Ice Master is a deceiving game whose concept is so origi-
nal that it defies classification. There aren't many different
enemies attacking, but the mosquitoes are fast and very
smart. The blocks of ice are your only defensive weapon in
the game in addition to your craftiness of forming the blocks
of ice.

I found Ice Master to be a refreshing change of pace from
the run-of-the-mill shoot-'em-ups. Forget about spaceships,
laser beams, and firing rockets. Just watch out for those
nameless mosquitoes that flit, skitter and swoop around on
your CoCo screen. Its originality and fast-paced action were
the first things to capture my attention.

COLOR KEY COMMAND

(.'< >L< >R KEY COMMAND is a BASIC programming aid that
will speed the entry of your programs. You can increase
your programming speed by as much as 50".,. Instead of
having to type in all of the BASIC commands, you can
simply press a control key, and then press one other key
— the BASIC word is entered for you automatically! You
can also activate the automatic line numbering mode,
then every time you press enter a new line number is
entered for you. You can select the start line and the in-
crement. Ever wanted to copy lines you have already
entered? Now you can. Simply type in the line number
you want to copy, then type in the new line number. The
new line is immediately displayed and you are put in Ex-
tended Basic's EDIT Mode. Either edit the line, or press
ENTER. (This command is not available to those with
non-extended Basic users.) How about merging programs
together from tape? Those with Extended Basic do not
even have to worry about proper line numbering, COLOR
KEY COMMAND will RENUMBER each program as it is
loaded into memory! COLOR KEY COMMAND also has
four custom programmable keys! Each key is capable of
holding (i4 characters each! How would you like one but-
ton entry of 64 characters? What else will COLOR KEY
COMMAND do? One button RUN, CLOAD, CLOADM,
LLIST, LIST, RENUM, MOTORON, MOTOROFF,
AUDIOON, AUDIOOFF, TRON, TROFF. Those with disk
systems get one button BACKUP, DIR, FREE, and also
you can print your directory to the printer with the touch
of a button! You can turn off the program any time by
pressing the CCMD OFF button. How can we offer so
much for so little? We made templates that you can cut
out yourself. You do about an hours work or less and save

about $8.00. That is how much more we would have to
charge if we did the work. You save in the process! You
can also reprogram the prompt, no more "OK," and select
the cursor color you want.

DOUBLE DOS BASIC

364,000 BYTES!

That's right! Using your 64K Color Computer, and an 80
track drive, you too can have more than TWICE as much
storage on your disk drive system. DOUBLE DOS BASIC
allows you to use 35, 40 or 80 track (double or single sid-
ed) drives all on one system, all at the same time! Your
system could consist of a 35 track drive, a two drive
AMDEK system, and an 80 track drive, all working, and
hooked up to your system! (The AMDEK drives are 40
track drives.) ALL commands are supported in DOUBLE
DOS BASIC. The DOS is totally transparent to your
BASIC programs! If your system selection is 80 tracks, a
PRINT FREE command will return 158 granules! Com-
pare this to the 68 granules your system now returns! The
40 track drives would return 78 granules, 10 more than
the 35 track system. EVERY command in BASIC is sup-
ported by DOUBLE DOS BASIC. If you haven't already
upgraded to 64K, now is the time! Use your system to its
FULLEST! DOUBLE DOS BASIC also gives you RESET
PROTECTION, unlike most of the other 64K programs.

GALATIC MATH I w ^

GALACTIC MATH is not like any other math tutor program on the market
for the Color Computer! This program has been written as an arcade
game! The player becomes involved in playing the game and forgets that
he/she is supposed to be learning! The student must enter the answer to a
math question that is shown in the body of a flying saucer moving down
from the top of the screen, There are four saucers moving down from the
top toward the player. The player must maneuver his base under the
saucer, enter the answer to the problem, press the spacebar to fire the
laser. A new saucer with a new problem replaces the one just blasted. The
score, time in play, number of hits, number of misses, and number of
bases left to the player are displayed at the top of the screen. All of this is
in high resolution graphics using the new 4 color mode on a black screen!
There are four levels of difficulty, and you may select either addition or
multiplication. Don't bore your kids with smiling clowns or happy fares!

DDH Directory-File Builder

An Enhancement For

Disk Data Handler

There are so many ways to produce a disk directory that
all of them would not fit in a 64K machine — they all seem to
revolve around DSKIS.

DDH Directory- File Builder is no different in that
respect. The difference is that this routine uses the power of
your database program to do what it docs best, manipulate
data.

The trick is to read your disk directory and write it to a file
in the format that can be read by your database. The objec-
tive is to minimize processing time. There was a nice BASIC"
program published in 80 Micro which would read each disk
and collect the data into a master directory, a complete
library list. 1 patched Qsorlbin from the June issue of Rain-
how SO the program would have a M/ L sort routine. Even
with this patch and three second sorting lime, execution for
each disk approached four minutes when dealing with three
or four hundred records. I have a lot of data files.

The beauty of having a master library is to be assured that
you have properly backed up those important disks with all
the programs included.

The heart of the program is writing the data in the
appropriate formal which can be read as a standard file. In
the case of Disk Data Handler, all records are handled as
strings, making the conversion relatively easy.

Program execution is simple and fast. As quickly as the
drive can read a directory, you are prompted lo insert
another disk or END. This routine can continue until you
have about 500 program titles in the buffer of a 32K
machine. You must then save this data to a file.

II you have more than 500 titles, you can resume with
another session. Upon completion of reading directories,
you must run DDH and load the directory files. Using the
typical directory information, i.e., name, extension, type,
format, and size, plus a disk label of 10 characters. DDH will
process over 1500 records with the 64K version.

Sort time for 550 records was 1 5 seconds. 1 chose to add a
40 character "comment" field to each record which reduced
the capacity of DDH to 500 records.

The best feature of DDH Directory- File Builder is that it
provides an accurate, no hassle software inventory quickly.
A hard copy listing can be customized to your needs through
the reporting feature of DDH.

The directory program listing (it's very short) is being
included with the DDH package at no extra charge. If you
would like a copy of the listing, send a S.A.S.E. to Custom
Software Engineering.

VC Wargame Called
Good Simulation

"You've been in 'Nam 90 days now but sometimes it feels
like forever. No matter how well the Viet Cong are thrashed
one day, it seems they're back in even stronger numbers the
next." If this sounds like a very unpleasant scenario, it is, if
you are in it. To warmongers, it's a boon.

VC is a new simulation for the Color Computer, that is
different from all others. You are in charge of the Huy Bihn
Province with 10 ARVN (Army of the Republic of South
Viet Nam) units. Your mission is to eradicate VC activity in
your area.

After watching a good title page you have the choice
between six levels of play. Zero is very easy, while level five is
nearly impossible. The board then sets up your units in a
small bunch at the bottom of the screen. Small yellow
pyramids are put all over the screen with small gaps. These
represent neutral civilians. A neutral civilian could be one of
three things, a VC unit, a North Vietnamese Army unit, or
just a neutral civilian. How do you find out which one of the
above they are, the hard way, of course. You move one of
your units next to or on top of it. Vietnamese unit can
positively identify it. The Air Cav can't tell if it's an enemy
unit, unless it attacks you. To identify a civilian move a
ARVN next to or on top of it and if it is friendly it will
sometimes turn blue, if it is a VC it will turn into a red soldier

and attack you, a NVA does the same except that it is blue
and red.

NVA units are bad news. Fortunately, they appear only
on the higher levels. The artillery you can use to hammer
away a enemy units, but if you don't destroy them on the
first shot, you'll almost never get them. The VC turn neutral
civilians into VC by sitting next to them for an unknown
period of time or if possible will kill friendly civilians, which
gives away their position for artillery. The Air Cav can only
move into an unoccupied space, and artillery can't move. I
found, by accident, that you never shell friendly units, word
gets around and the friendly units all turn neutral!

The object of this madness is to destroy all enemy units,
without having more than half of the civilians become VC of
killed, after all how can you save a country if you destroy it?

As a wargame player, veteran of many battles in space,
air, land and sea, 1 would rate the game high for a computer
simulation. The documentation was a bit confusing since the
Apple. TRS-80. Atari, and IBM instructions are mixed in.
but not beyond comprehension. It is very nicely packaged in
a box case with a picture and a description on the back. It
includes the Atari and Model I — 1 1 1 versions as well as the
Color Computer version. It runs in 16K tape and works
without a hitch with a disk drive. You can use the keyboard
or joystick to control movement.

FILMASTR

The Color Computer has a powerful ally in FILMASTR. This is a DATA
MANAGEMENT SYSTEM that you can trust. FILMASTR combines
the best features of the big systems to provide a combination of
speed, power, and ease of operation that can't be beat.
YOU are in complete control of this friendly program with no program-
ming knowledge required. You design the data screen with up to 20
fields by moving the cursor or screen with the arrow keys and typing
in the field names. FILMASTR takes care of all of the rest.
Enter data by just filling in the blanks. This form fill-in is easy and
natural to use. You can even copy data from the previous record with
one key-stroke. Add records, delete records, change records without
fuss.

Tell FILMASTR to sort your file on any field that you want or to re-
trieve a particular record and the job is done with super-human
machine language speed. FILMASTR will find a single record or a group
of records that meet your request and will save those records as a
separate file if you want to.

Controlled printing formats? Of course! Tell FILMASTR which records
to use, which fields to print and in what order. You can control the
print location to any position on the page. Mailing labels? You bet 1

All commands are given to FILMASTR with single key strokes. Press
the HELP key (BREAK), and the available commands are displayed.
Make your choice from the menu and let FILMASTR do the work.
FILMASTR can store up to 955 characters in each record and up to
24.000 characters in each file (9000 with 1 6K).

Battle: A Little
Game That Grows On You

rsz\

When In Rome
Count Roman Numerals

As a wargamer of some 20 years experience, I tend to
think of the simpler games as rather trivial, so when I
CLOADMed Aurora Software's Bailie, the thought "jusl
another battleship" came to mind. Well, not quite!

Battle is a two player game (with reasonable solo play
capability) in which the two players take turns searching on
the same low-res map for enemy ships. This has the unex-
pected effect of placing the two players in roughly the posi-
tions of allied destroyer captains searching for members of a
hidden U-boat wolfpack. Each wants to make the kill, but
the best chance for success is through cooperation with the
other ship commander so that both may work at full effec-
tiveness. If the players only compete against each other there
will be a winner, but the winner will have a lower score than
if the players had worked together to set out a formalized
search pattern.

In addition to 12 hidden boats, there are 12 "bombs" (1
think of them as mines) concealed in the map grid. A player
is out of the game after hitting three "bombs." These and
other details are listed on a short, but adequate instruction
sheet.

At game start, players enter their names, which are dis-
played on the screen along with a running total of the scores.
Also on the screen arc the 10 x 20 /.one map. a listing of the
number of boats left unsunkdhe 12 boats range from two to
five units in length), and a score of "BOM US HIT" by each
player. A prompt in the lower left corner shows whose turn it
is.

All in all. Aurora Software has produced a neat little
game suitable for family play or cut-throat competition.

Mark Chamcy. of Dcnville, New Jersey, writes. "I tho-
roughly enjoyed Jim Hall's article ("Graphics Special — The

to produce various patterns with all the graphics commands
except PCLS.

"After toying the some PEEKs and POKEs. I discovered
that POKEing location 179 gives me various backgrounds
when PCLS is used."

That's also a good idea in most American elementary
schools, where learning the Roman system is a traditional
task. Whether you want to write outlines for English papers
or simply figure out copyright dates for movies. Moreton
Bay Software has a program. Arabic Numbers: Roman
Numerals, that will help youngsters (or remedial adults)
learn the conversions.

The program is straightforward: Two tutorials teach the
conversions and a third tests the students on their mastery.
The tutorials present the numbers and numerals in sequence
to help understand the significance of the Roman symbols
M. D. C, L, X, V. and I. Teaching in sequence, I believe, isa
minor flaw in the program, since it permits students to guess
ahead and thus avoid the necessary monotony of memoriz-
ing the code. The program unnecessarily increases mono-
tony by sending students back to the beginning every time
they make an error in the initial learning phases: thus it does
not always reward them for items they previously mastered.

Once the basic conversion has been learned, the students
are tested and the program provides bells and whistles for
right answers and a raspberry for the wrong ones. It also
keeps score and gives praise in the form of number puns:
"GOOD 4 YOU. "The program will supply correct answers
to missed questions, but it curiously Hips to its "RIGHT"
mode after giving the answer, possibly giving students the
mistaken impression they answered the item correctly.

The programmer missed a good bet, I believe, in not
drawing on the potential of the CoCo(or any computer) to
allow a student to break Roman numerals into their constit-
uent parts on the screen and then figure out the numerical
significance of the clusters. For example, instead of simply
supplying a numeral:

MCMLXXXIV

and asking the students to decode it, the program could have
reinforced skills by letting the student break it down on the
screen something like this:

M=

1000

CM= 1000- 100=

900

LXXX=50+30=

80

1V=5-I =

4

MCMLXXXIV= 1984

Nevertheless, Arabic Numbers: Roman Nwnerals"works."
teaching the conversions efficiently and accurately. The only
complaints I heard from students were that the program was
a little dull. It was agreed, however, that the program was a
lot better than learning the same material in an arithmetic
textbook.

The instructional manual is clear and helpful, and it con-
tains some excellent supplementary information on the orig-
ins of Egyptian. Roman, and Arabic number systems.

Getting Even With
The Byte Bat

1 was keying in the seventh page of an eight-page
Adventure game, hours upon hours had passed — just one
more page and I could play that long awaited game — when
it happened. The telephone rang, I answered it, turned to
glance at my CoCo and the screen was snowy. Beau, our
overzcalous retriever, had gone behind the table to "retrieve"
his play duck and disconnected the computer. 1 hung up the
phone and Beau fled in terror, knowing the fury that was
about to ensue. 1 ran to my secret hiding place, grabbed the
bat, dashed to the CoCo and beat the keyboard and monitor
with it. screaming every expletive known to mankind — 1
even made some up.

Yes, my chips were down but they weren't destroyed
because they were the victim of my Byte Bat. a 1 7-inch soft,
foam rubber "aggression/ frustraton" bat, by MicroTie Sys-
tems Corp. This light blue "anger reducing device" is an
accessory no computer user should be without.

The Byte Bat comes with a witty user's guide, an 1 1 x
17-inch "Strike Back" wall poster, a decal which says
"Warning, this computer friendly liveware is protected by
Byte Bat." and a button.

There are three recommended "digital interfaces," or
ways to grip the Byte Bat. The first is the Bi-Bit Grip, which

should be used when you feel only a little stress and frustra-
tion. Using the thumb and index finger, firmly grip the bat
and smash away. Care must be taken when using this inter-
face because of its two-finger flimsy grip — the bat may fly
out of the aggressor's hands and into an innocent co-
worker's (or family member's) face.

During those days of high level frustration, using the
Binary Grip is most comforting. This grip uses the thumb
and four fingers — like the customary tennis grip, it's kind
of like clenching your fist. Get the picture?

Thirdly, and deadliest of all, is the Byte Grip, using the
thumb and seven fingers from one hand. This interface is
recommended only in extreme cases, such as system failure
or job failure (when you are thinking of ways to kill your
boss ... or retriever).

The Byte Bat is used and measured in "B.A.U.D." Rates
(Basic Aggressive Units of Dissatisfaction) which range
from one to 12,876.453. There is a warning for B.A.U.D.
rates in excess of 100 — it may be hazardous to the aggres-
sor's wrist, arm and psyche. My B.A.U.D. rate has been
measured at 12,000. Care to top that?

The user's guide also includes hardware and software
applications. For example, "Use of the Byte Bat is recom-
mended when: You set up the printer to print the listing for
your new program overnight, and return to find that all
25,000 lines have printed on topofeachotherduetoa paper
jam. "Or my favorite, "When your speech synthesizer begins
to stutter or speak only Portuguese."

But what about the little darlings at home to destroy your
computer work? Well, "liveware applications" are also
included in the user's guide. "Use of the Byte Bat is recom-
mended when: Your three-year-old washes all your discs for
you, as a special treat." And, yes, it is recommended for all
computer widows and widowers.

As you might have guessed, the Byte Bat is excellent for
office use. 1 1 has been a favorite frustration device here at the
Rainbow. When it arrived, the editorial and art departments
gathered around for the unveiling. Everyone got their turn
at bat, too. Now it is only used in serious applications — like
deadline week, or a partial crashing of a Rainbow On Tape.

1 recommend the Byte Bat for all computer users. It can be
used for the office or at home, although the carton warns
that it should be kept away from children under the age of
three, since pieces of the foam rubber may be bitten off and
swallowed. The Byte Bat is fun, and most importantly,
serves its purpose — as a safe, frustration relieving way to
beat up your CoCo, or any other person or animal who
stands in your way of computing. Who says man's best
friend is a dog?

Hints . . .

Disk or Cassette I/O Errors?

Make sure that the disk drive(s) and cassette recorder are
not on the left side of the TV set (or if they are, that they're at
least half a foot or so away). This is because the flyback
transformer (which is almost always on the left side of the
TV) puts out a great deal of RFI that can interfere with
cassette or disk operation.

THE UN-DISK

But true! There is a disk
drive in your Color Compu-
ter .. . and it is faster and
more efficient than any
"hardware" drive you can
buy, for any price. This new
"disk drive" is called VDOS—
for Virtual Disk Operating
System— and it will absolutely
revolutionize the way you
operate your CoCo.

VDOS lets you use the
"extra" memory inside your
CoCo as a virtual disk, with
programs (any programs)
stored out of the way. You
can "save" and "load" pro-
grams from your in-memory

disk into working memory,
and then run them. When
you're done, you can simply
access your in-memory disk
again . . . and save or load
another, and another.

And VDOS is fast.
Because you are using
memory rather than a
mechanical device (like a
disk drive or cassette
player), programs load
instantly. Yes, VDOS is fas-
ter than a disk!

VDOS works with all
Color Computers— from
16K non-extended to 64K
extended. Obviously, the

more memory you have, the
greater number (and
length) of programs you
can store. For a 64K sys-
tem, VDOS also uses the
"unused" part of memory,
providing up to 50,000
bytes of storage! Now,
that's some disk!

We call it VDOS because
in the future there will be
utilities for your VDOS
UNDISK that will give even
greater capabilities — such
as a full one-pass memory
dump to cassette. Other
utilities are planned, too.

We believe VDOS is the

greatest advancement for
CoCo since the introduc-
tion of the disk drive itself.
And, at less than $100, it is
so inexpensive you can't
afford to be without it. If
you have the "cassette
blues," VDOS is the answer!

Finally, VDOS is simple to
operate. It is entirely self-
prompting and comes with
a complete manual. But you
almost don't even need the
instructions— it requires
absolutely no technical
expertise.

VDOS. The answer to
your prayers.

Deadly Duology
Death Dreadnaught

From the eerie interior of a wrecked starship comes an Adventure unlike any you
have ever played. This program is so violent in its descriptions and so deadly in its
playfield that caution is advised in allowing small children to play it unsupervised.

You are exploring the wrecked interior of an alien vessel that has been utterly
devastated from within. Its crew has been murdered, its engines fused and destroyed.
Your job is to escape. Because whatever did all this knows you are here.

Get food. Get air. Get batteries. Get what you need and get it quickly before whatever
it is that lurks in the shadows gets you.

Death Dreadnaught is traumatic, dramatic, ecstatic and dynamic in a way only Text
Adventures can be. Every word oozes of the danger that awaits you if you tarry too long.

Rated R due to extreme descriptions of violence (may be too intense for
children under 10).

Death Dreadnaught, $19.95, shipped postpaid to your galaxy today.

The Domes Of Kilgari

The spine tingling sequel to Death Dreadnaught is now a reality.

You've escaped from the Death Ship only to crash land on Kilgari, the most desolate
chunk of rock and sand in the universe. Your only hope for continued survival —
penetrate the Ion station and get enough fuel rods for liftoff.

But there's a presence here that somehow brings back memories of that nightmare
aboard the Dreadnaught. Could it be that the hellspawn creature you left behind has
somehow caught up with you?

Interspacial Digitron has trapped and wired the domes so that intruders are de-
stroyed. If you can get the rods, decode the alarms and return to your ship, you just may
be able to go on breathing.

Domes Of Kilgari, the ultimate space Adventure, is uncluttered by pictures or graph-
ics of any kind. It is pure descriptive english that gives you the clues. Your wits against
that of Digitron and the nameless fury that dogs your trail.

Teee Off/: A Challenging
Round Of Micro-Golf

Teee Off/Ms a golf game for a I6K Extended BASIC CoCo
or'I DP-100. The game comes ona cassette with a two-page
instruction sheet. Teee Of /f can be played by one to four
players, each player taking his turn at each hole in rotation.
Unlike the real game of golf, each player is required to
complete each hole before the next one can start. However,
all players must complete a hole before any of them can
continue to the next. The game is played with the right
joystick, as are most single joystick games.

The game consists of nine holes of golf. Each hole is
comprised of a series of sand traps, water'traps and cactus in
place of trees. I guess the writer lives in the southwest where
there is an abundance of cactus. If a player wanders into
either the sand traps or the water traps, he is required to play
his way out. In the real game, that is true for the sand trap.
However, when a shot is placed in the water, the player is
required to drop another ball no closer to the hole than
where he entered the water and take a penally stroke. This
version allows the player w play his way out of the water. Ol
course, each stroke must be quite firm and strong or the ball
will hardly move at all. This could make it very unwise to
take a shortcut across the water trap.

The ball is hit by placing the golfer and club such that the
tip of the club is just touching the ball. The angle between the
club and the ball will determine its direction. The golfer will
always wind up in a counterclockwise direction. Once the
golfer is positioned, holding down the firing button will start
his windup. The longer the fire button is held down, the
larger his windup will be and the further the ball will travel.
That is. unless an obstacle is encountered. Thus, the distance
the ball is to travel is dependent on the amount of windup
and any obstacles in its path.

Once the ball has been hit to the green, the screen will
change and present an enlarged green. The method used
here is the same as on the fairway, except now the ball will
travel further with a lighter stroke— the characteristics of a
true green.

The entire procedure is repeated for each of the remaining
holes. Once all nine holes are finished, the round is complete
and the game can be restarted for. say. the back nine.

The game is loaded from cassette using the CLOADM
"TEEEOFFF" command. Once in. the program is started
using the EXEC command. The game presents a grid with a
square in the middle of it. Instructions are presented indicat-
ing that if the color of the square is not blue, press the reset
button until it is. Once completed, you are ready to start the
game. You will be asked for the number of players which will
be playing. In all cases but one. 1 only used the one-player
option. As you progress around the course, you will be
presented with various par holes, which perform doglegs to
the right and left.

In playing the game, 1 found the graphics to be ol good
quality, the course was well laid out with the usual amount
of hazards presented. The motion of the ball is smooth and
the club swing consistent. The player is sort of a stickman
who on some occasions has the nasty habit of being split
between the right and left part of the screen. If you are
playing near the borders, that part of the player extending
beyond the boundary of the screen appears on the other side.

1 did gel into some positions from which 1 found it impos-
sible to hit the ball in the manner 1 wanted to. In one case, on
the filth hole. 1 found myself about one inch from a cactus.
Each lime 1 tried to hit the ball toward the cactus, or even

near the cactus, the ball would not move, but 1 did receive a
stroke. Al first, 1 thought I was not properly positioned on
the ball, but then I noticed that the stroke count was going
up. 1 was forced to play a shot parallel to the cactus in order
to move the ball. Once il was above the area of the cactus, I
could play the shot I had wanted to.

When the ball hits the out of bounds marker, it has a
tendency to slide along the out of bounds marker like it was
a wall. I found it takes quite a bit of practice to get the player
positioned where you want him. In some cases, the response
to the joystick movement seemed quite sensitive and. in
other cases, it was almost nonexistent. I found that the fine
adjustment took quite a bit of practice and patience.

All in all, I found the game to be amusing and fun to play,
as long as the player could live with the positioning difficul-
ties. 1 enjoyed the game and actually found myself getting a
birdy on seven, the second time around. The graphics are
good and the player action is smooth. The ball travel is
smooth and consistent from round to round.

The game is fun and challenging. It represents its real
challenge in the form of par. as it should. It is not easy to gel
par on some of the holes, and 1 believe that is the way it
should be. 1 did find that a return to center joystick would
help considerably, but that is due to the way Radio Shack
joysticks are built and not a fault with the game. The game is
fun to play and does provide a fairly good challenge to break
par.

Color Tutor — A Meat
And Potatoes Utility

Many people who are contemplating purchasing a com-
puter often ask the question. "What do you do with your
computer?"! can think of a number of reasons for owninga
computer, but they usually don't impress the person asking
the question. Learning programming or playing games just
doesn't cut the mustard in the minds of those who see the
computer more as a tool than a hobby. Even balancing the
family checkbook doesn't go over since most will argue that
they can do it faster with a calculator. However, those of you
with school-age children have a ready made justification
— education. By education 1 don't mean learning BASIC
—not everyone has to be a programmer. But, as everyone
knows, the computer is a very useful tool for presenting
material to youngsters that they must learn by rote such as
state capitals, vocabulary drills, foreign language, math
problems, etc. Color Tutor by Elite Software is such a tool
to assist in this endeavor.

Color Tutor is the kind of program that everyone says
they will write for Johnny orSuzie when they first buy their
computer. But let's face it, not many of us do it. The pro-
gram comes on tape, but a disk version is also available. It
can be used with a I6K machine but requires Extended

BASIC. After loading the program and typing RUN (the
program comes on a non-protected tape and can be saved to
tape or disk and since it is written in BASIC it can be modi-
fied), the following menu appears:

(1) TYPE NEW LESSON

(2) LOAD LESSON FROM TAPE

(3) EDIT LESSON MATERIAL

(4) SAVE A LESSON TO TAPE

(5) STUDY LESSON

(6) EXIT PROGRAM

While all of the items in the menu are self-explanatory,
several comments are in order.

To prepare a new set of questions and answers, one selects
item I from the menu. Color Tutor then requests the number
of questions to be entered and then prompts you for each
question/ answer pair. A maximum of 50 questions may be
entered, however in a 16K machine it is suggested that the
question length be limited to 32 characters, but with a 32K
machine the question length is 64 characters. For most drill
type questions this is not a severe limitation.

Option 3 is provided to permit editing of a lesson. Now
this is not a word processor type editor. Color Tutor simply
asks for the number of the questions or the answer or both.
Since the type of questions and answers which you might use
with Color Tutor will usually be short, this type of editing is
not a disadvantage. One interesting aspect of the editor is
that it is password protected. The purpose of the password is
to prevent the student from accessing the questions and
answers through the editor and thus alter them. While it is
interesting that Elite took the time to add this option, it is

disappointing the way they handled it. The user does not
have the option of choosing his own password which could
be saved with each lesson — a simple item to program.
Rather, the password is specified in the program and can't
be changed by the user unless he does some rcprogr'amming.
This is an item that I feel Elite could improve upon.

Option 5 is chosen when a lesson is to be studied. Upon
choosing this option. Color Tutor will randomize the ques-
tions and then present two options for choosing the correct
answer. With the first option, the answer must match the
correct answer with the exact spelling. The other choice
checks the spelling of the answer with only the first three
characters of the correct answer. Each question is then
presented and a score of the correct vs. wrong answers is
kept. At the end of the lesson the student is presented with
the option to repeat the lesson.

Color Tutor performed exactly as described in the brief
but adequate directions. To check out the program I chose
to enter 50 questions — the limit of the program. For my
questions 1 chose the state capitals. After entering the ques-
tions, I first saved the lesson to tape. It prompts the user for
the file name and then immediately starts the recorder, ie.
Color Tutor does not prompt you to set the recorder to
record mode. Fortunately. I anticipated this possibility and
had the recorder ready. This "glitch" should obviously be
corrected as it is bound to cause some inconveniences for
most people. Almost every program which I have purchased
provides a prompt to ready the recorder. 1 would hope that
Elite would take care of this problem. But. once loaded, the
lesson ran as expected — of course, 1 didn't know all the
state capitals and I won't mention my score either.

Color Tutor is a meal and potatoes program. It does what
it is supposed to do, which is better than a lot I've seen. In
other words, no bells and whistles or blinking lights or
musical renditions — some might argue that this is a disad-
vantage since reinforcement for a correct answer makes
learning more fun. But. the important thing is that it is a nice
little educational utility program to have around when there
is the need to review school assignments.

The major limitation to Color Tutor is in the method of
answerchecking. Either the answer must be spelled correctly
or the first three letters are checked. This is okay for single
word answers but obviously a problem for the more com-
plex answer. For those who feel that this is a severe limita-
tion. I would suggest the more sophisticated CA1 type pro-
grams such as Radio Shack's Color PILOT, which is also
considerably more expensive. However. I think most will
agree. Color Tutor is very useful in the home when there is
the need to study material such as mentioned above. 1 defi-
nitely recommend Color Tutor, but I personally feel that it is
slightly overpriced.

Mansion Of Doom —
A Fun, High Quality Adventure

Webster's dictionary definition for 'adventure' is "an
enterprise or performance involving the uncertain or un-
known." However, I do not think that he had a computer
Adventure in mind when he wrote that.

Mansion of Doom, by Pal Creations, is a high quality
Adventure game made for the 32K Extended BASIC Color
Computer. It comes on an easy to load five-minute tape with
a single copy saved on each side. The instructions say to
unplug your disk interface, if you have one, before loading
the program, which would then make it very inconvenient to
use for people with disk drives. However, I have discovered
that a simple PC LEAR will allow you to run and save the
program to disk with the disk interface plugged in.

The program takes exactly two minutes to load from
cassette, and about eight seconds for a disk. It is written in
100 percent basic and is almost I8K long. There are no
graphics in the program, but that is more than made up by
the 76 rooms, 65 objects, 1 1 user verbs and six different
directions(U,D,N.S,E.W,). The instructions, although only
half of a single side of a piece of paper, are sufficient. There
are instructions in the program also. It seems that the pro-
gram could have been put on a 16K computer if they had left
out the instructions and stripped and compacted the pro-

gram with some sort of compresser program. As to why they
didn't, I really don't know. It would have allowed a wider
range of people to purchase the program.

You have been chosen to rescue Princess Marlena who
has been kidnapped by the evil Count VonSteinhoff. To do
that, you must enter his mansion on the edge of town and try
to find her, hopefully alive! Others have gone inside the
mansion, but not one of them has ever left!

Once you enter the mansion you are met by vampires,
bats, werewolves, and other creepy creatures. You can. as
previously mentioned, travel in six directions, which is in my
opinion, a welcome plus. However, there are only 1 1 verbs,
which is rather inconvenient. For example, I like to use the
word TAKE when I would like to acquire something. But
the program only recognizes GET, and I was continuously
bombarded with a screen of all the available commands
(another plus) when I forgot to use GET instead of TAKE.
Also, there is no way to save your position to tape, so you
can quit and continue the game where you left off later on. It
shouldn't be a problem for the more advanced adventurist,
who should be able to solve the adventure in about four to
five hours, but if you aren't that good, be prepared to spend
the night.

I could only find one bug in the program. When you get
chained in the shackles, the only way to get out is to type
"YORL."l couldn't find any other ones, although when you
get to some certain places, you might think you are in an
endless loop. You actually aren't, and it is not a bug in the
program. Just be patient and you should eventually get out.

In conclusion. I think it is a fine program for most people.
I would not recommend this for beginning or extremely
advanced adventurists. Its level of play is most suitable for
someone in-between. The price of S 1 4.95 is. in my opinion,
rather high for a non-graphic Adventure game, but it is a
very good program, and should give you hours of fun.

• 9 Hi-Resolution Display Formats: from
28 to 255 Columns by 24 lines

• True Upper/ Lower Case Display

• Automatic Key Repeat

TEXTPRO III is the most advanced Text Editing and
Word Processing System available for ihe Color Com-
puter. One of the reasons for this is, Textpro works in a
totally different way than the other Color Computer
Word Processing programs. It uses simple 2 character
abbreviations of words or phrases for commands. These
commands are used at the beginning of a line and are
proceeded by a "." period. Several commands can be
chained together on the same line for ease of use. Thru
these commands you tell the Word Processor how" you
want the margins set. line length, indenting information,
and so on. You can change the way you want a docu-
ment formatted at any point in the document. You also
have the freedom to write without worrying about how
long the line is or where the margins are and so on. The
Word Processor automatically takes words from one line
to the next and fills out the printed line to the desired
length. You can even use the command to Input Text
from the Keyboard while a document is being processed,
and use that information to change the formatting or
enter any other valid text Processor command. With this
kind of flexibility and an extensive set of commands and
functions available, its no wonder that TEXTPRO III is
the most advanced Word Processing System.

easily switched to any other format available. Along with
the Hi-Resolution screen we added automatic repeating
keys "Typomatic." The rate is fully adjustable from ultra
fast to super slow or can be turned off entirely for your
convenience.

64K Support

Textpro III fully supports the use of 64K on the Color
Computer. It has fast automatic memory sensing and
configures itself accordingly. Texlpro III does not require

The Mini Modem And
Colorcom/E: An Easy
Way To Get Connected

by Ed Ellers

Greta Garbo once said "I want to be alone," but a lot of
computerists would disagree when it comes to their systems.
Many people are interested in getting their computers
hooked up to the outside world of bulletin boards, informa-
tion services and computer-to-computer communication
over telephone lines. With the "Information Age" in full
swing, one could argue that having a computer without a
modem is almost like not having a telephone in your home.

Mura's MM-100 Manual Mini Modem is a low-cost
alternative for those who want to jump into data communi-
cation without much of an outlay. For under S80 you get a
unit that does everything a modem has to do. The MM-100
will make the connection between your computer (not just
the CoCo, MC-IO and Dragon, but almost any personal
computer) and the phone line: the catch is that you must
switch it on and off manually. The Mini Modem does not
hang up at the end of a call, answer incoming calls automati-
cally or dial numbers. Even so, the Mini Modem is very easy
to use; it's simpler in some ways than more sophisticated
modems. (The Mura is very similar to the Radio Shack; TDP
Modem 1; its operation is almost identical to the Modem I.
but the Mini Modem's circuitry is much less complex.)

The Mura unit is a direct-conncct modem, which means
that it plugs directly into your telephone line jack (as
opposed to acoustic couplers, which have a cradle in which

you place the handset of your phone). It is, of course, FCC
registered, and legal to use on phone lines in the United
Slates. One note here is that in some states local telephone
companies are allowed to charge an extra monthly fee,
which ranges from fifty cents (in Vermont) to S49.50 (in
Oklahoma), for the privilege of using their lines for data
communications, or in some cases for using another device
on the line. In a few slates, you must have business service (at
its higher rates) on the dubious grounds that if you are
transmitting data you arc "using the telephone for business
purposes." Before buying a modem, check with the tele-
phone company in your area about the tariffs governing
modem use; if they don't tell you what you want to know, try
your state's regulatory agency.

The instruction book does correctly tell you to notify the
phone company when you connect the modem, but this is
only a legal requirement since the Mini Modem does not
place an additional load on the line and does not affect the
operation of the phone company's equipment or (when it's
switched off) your phone service. To get it going, you just
unplug the phone nearest to the computer, plug the modem's
cord into the phone line jack, plug your phone into the Mini
Modem's jack and then connect the modem to the compu-
ter's SERIAL I/Ojack. (Spectrum Projects sells the modem
with a cable to connect to the CoCo.)

With the Mini Modem, a telephone (and of course the
Color Computer), the only other thing you need is some
kind of terminal program. The standard in the field. Radio
Shack's Videotex cartridge (and formerly cassette), was
designed strictly to communicate with information systems:
you can't "download"a file (such as a program), save infor-
mation to cassette or disk or print out what you receive.
Along with the modem, I received a copy of Eigen Systems'

Disk Colorcom/E Version 2, which is primarily what I used
to test the Mini Modem.

With Colorcom/E Version 2, you can:

• Download a file (such as a BASIC program or a news-
letter) from the computer on the other end (kndwn as
the "host").

• Upload a file from your CoCo to the host system.

• Print out a copy of any or all of your communications,
or save them to disk.

• Do "auto log-on," which means that Colorcom-E
automatically types in your name, account number,
password or whatever you would normally have to type
when getting on a system.

• Read the incoming messages on a 51 -column, 24-line
screen with both upper and lowercase letters.

• Display weather radar maps, financial index charts and
game graphics from CompuServe and some other
systems.

Color com J E Version I was reviewed in the Rainbow in
November 1982. Version 2 has added the 5 1 x 24 upper/ low-
ercase display mode (much like that of Telewriter); it's a big
help because most of the systems that you will be "dialing
up" use a greater line width than the 32-character text screen
built into the CoCo.

Disk Colorcomj £"V2" (as Eigen Systems calls it) has a
menu that lets you select auto-logon sequences for several
services. You can edit the files for the various procedures,
and then set up the menu to select them. To log on to a
particular service, you first press a number key for the
service you want. When the file has loaded, the screen will
show the phone number for that service (which you put in
earlier). After you make the connection. Disk Colorcom/E
will type in the account number, password or whatever
needs to be typed. That's it! ( I'm told that a cartridge version
of Colorcom/E V2 is almost ready to be released; if you
intend to buy the cartridge, ask about the availability of
Version 2.)

The Mini Modem, like most modems, has two modes
called "originate" and "answer." In general, you use "origi-
nate" when you make a call and "answer" when someone
calls you. To call a bulletin board or some other service, you
pick up the phone and dial the number and wait for the
computer to answer. When you hear the high-pitched
"answer tone," switch the modem to ORIGINATE and
hang up the phone. If somebody calls you (say to transfer
files), you pick up the phone and switch the modem to
ANSWER; when the green CARRIER DETECT light
comes on you hang up the phone. In either case, after you
disconnect from the other system and the CARRIER light
goes out, you would switch the modem off to hang up. (If
you forget to turn it off, your line will remain busy.)

Using Disk Colorcom/E Version 2,1 logged on to all the
local bulletin boards at numerous times (driving one of the
sysops to the point of distraction) as well as two out-of-town
BBSes and CompuServe and The Source, using local and
AT&T and GTE Sprint long-distance connections. In every
case, the Mini Modem performed flawlessly, without a sin-
gle character garbled as far as I could tell.

If you want to get on-line without emptying your wallet to
do so, the Mura Mini Modem and Disk Colorcom/E
together are one of the best ways to do it.

Screen Reference Card
Is No Ace!

It's very nice to find a program thai does what it claims to
do and is very easy to learn to use. Screen Reference Card
(also known as SRC) is just such a program.

Unfortunately, there's nothing else good that 1 can say
about it.

As the name implies. SRC is designed to put reference
information on the screen so that you won't have to look it
up in a manual or on a reference card.

On loading the program, you are presented with a menu
that invites you to press 1 to 9. Pressing 9 crashes the
program on an Undefined Line Error. Options 7 and 8 are
reserved for "user defined" routines. That leaves six selec-
tions that actually do anything.

One choice will show "statement and function syntax."
What you get is several screens that list various commands.
You view different screens by using the up and down arrows.
Among other things, you'll see a whole bunch of sample
format strings under "print using"— without the slightest
indication of the formats that any of them will produce.

"Operators and special characters" arc listed in an utterly
illogical order. The first line of this section tells you what the
plus and minus signs do, in case you didn't know, and the
third shows the asterisk and slash for multiplication and
division. Doesn't SRC's author know the priorities of
operators?

If you select "X/Y coordinates," about all you'll really
learn is that, on a graphics screen, there are 256 locations
across and 192 down.

"Text screen locations" is a screen that, if read in conjunc-
tion with the instruction sheet, will show you where the
PR/NT@ locations are.

"Graphic character codes" and "ASCII character codes"
are self-explanatory.

On the "user-defined" options, the instruction sheet sug-
gests that you might want to use one of them to write a
routine that will display a list of POKE locations. No sam-
ples are offered.

Think about it. In order to write such a routine, first you'd
have to make a list of the items to be included. And once you
have researched and compiled the list, what in the world do
you need the program for?

The whole premise of SRC is, in my opinion, flawed. The
author thinks it would be faster and easier to use his pro-
gram for looking up syntax and other information than to
use a reference card.

Trouble is. the time when 1 need to know where the
commas go in a CSA VEM statement, or what's the code for
a red checkerboard pattern, is the time when a program that
I'm working on is in the computer. It seems a waste of effort
to save the program in progress just so I can load SRC to
look up the answer.

For much less than the price of this program, you can get
the Nanos reference card, which is much easier to use and far
more informative. For command syntax, the red card that
came with the CoCo is usually all you need (in spite of a few
typos).

The Great Hamster Hunt —
It's Even Fun For Fathers

Oh well, another Adventure game. Time to type in all
those directions to find out where the hamster is hiding. But
wait, what's this? Graphics, sound, and some real adventure.
Maybe I'll take a look at this program.

The Great Hamster Hunt is not your everyday Adventure
game. Most games of this type have provided the user the
ability to move from room to room using one word com-
mands. The Great Hamster Hunt expanded this concept
into an enjoyable game for children, especially between the
ages of three and 10.

After the game is loaded and run. a map of the house is
shown. Each of the rooms is represented by an object that
would be found in that room. The picture of a bed means
bedroom, a stove is the kitchen, etc. The program user is
represented by a yellow and red square which appears on the
map. The square is moved from room to room on the map
using the arrow keys. Once the user is in the selected room,
the spacebar is pressed to enter the designated room. The
room is drawn on the screen and objects that might be in a

room of this type are drawn in high resolution graphics. To
move around the room, the user presses the arrow keys until
the yellow and red box is on one of the objects. The space bar
is then pressed to search that object for the hamster. The
search is continued until it is sure that the hamster is not in
that room. An M is pressed to return to the map and choose
another room. When you are in a room and hear some
spooky music it means that the cat is about to enter the
room. When the cat slinks into the room it is time for your
exit. Sometimes the hamster is seen scooting out of the
room, sometimes it is not seen. The hamster may change
rooms but it still might be hiding in the room. It may be
searched again later in the game.

When the happy music is heard, you have found the
hamster. The hamster is put in his cage. A well drawn picture
of the hamster is displayed and some lullaby music is played
to lull the hamster to sleep after it's long ordeal. The game
may be played again or stopped at this point.

My first reaction to the game was not extremely positive.
My five-year-old son took control of the game and had a
great time playing it. He was excited and even learned
something in the meantime. He was moving the cursor from
my verbal directions. Right, left, up, down. After the direc-
tions were explained, little difficulty was encountered in
understanding the game. Well, needless to say, my initial
reaction was wrong. The Great Hamster Hunt is a great deal
of fun. Even for fathers!

the basic C commands. CoCo Dos also contains features
which use the BASIC ROM functions (els. polcat. partial
floating point, etc.).

Dugger's Growing Systems has the cost effective C
for OS-9. It contains all the necessary C commands (while,
if, if else, int., char, etc.) which may be linked, loaded,
and used in a multi-user, multi-tasking environment.

The Premium: Micronix's
Finger-Walking Keyboard

The Color Computer keyboard has been the subject of a
great deal of criticism since it has been available. Many
people hate the Chiclet-like keys and snap action, although
some users do like it. When Radio Shack introduced its new
64K CoCo. it included a new keyboard with larger keys, but
the new keyboard is just as controversial as the old with
some people (myself included) saying that it's no big
improvement over the old one. A number of companies have
introduced full-travel keyboards for the CoCo, and several
have been reviewed in the Rainbow before. One of these, the
Professional Keyboard from Micronix, was reviewed in
March 1983. Micronix has recently introduced a new key-
board called the Premium, which is an improved version of
the Professional.

The Micronix Premium keyboard is available in two ver-
sions. One is used with the "old" Color Computer, which
had a RAM size button on the top; the other is for the "new"
CoCo, which has the nameplate centered over the keyboard,
and also the TDP System 100 and the Color Computer 2.
Each version is available for the same price, as opposed to
some upgrade keyboards that require an adapter to work
with the new CoCo and TDP-I00. The Premium (and now
the Professional as well) comes with a keyboard driver
program called Versakey, which makes use of the four
added function keys.

The unit that 1 tested was apparently an early model, and 1
got the manual for the earlier Professional keyboard. The
installation procedure is apparently identical to that of the
older model; I had no problem doing the job from the
manual. Absolutely no alterations to the computer are
needed, not even cutting down the center support post

(which some other keyboards require). In effect, all you do is
unplug the old keyboard, plug in the new one and place it on
the posts. One minor problem is that the holes may not line
up exactly with the posts, but this is solved by holding the
front of the case together firmly when you turn it over and
then putting the two front screws in first. Seven photos (in
the manual that I had) show you the exact procedure.

One thing that Micronix has improved over the earlier
Professional is that all the normal CoCo keys are placed in
the normal Radio Shack layout. The four function keys are
located to the left of the space bar; the bar is now one key
width off center, but if you are accustomed to the old CoCo
keyboard you will have no problem as the new bar occupies
the same width it did before and then some.

Unfortunately, the Premium keyboard has a number of
serious shortcomings compared to other keyboards. The
first thing you notice when you see the keyboard is that the
keys are placed a bit too high, so that you see the key
plungers under them. This detracts greatly from the general
appearance of the computer. Another is that the letter and
numeral keys are gray with white markings, rather than gray
with black as on the CoCo keyboard. The white symbols are
very hard to read and can actually slow down your typing if
you are in the habit (as 1 am) of looking at the keys as you
type. (I apologize to all the typing instructors out there, but
I'd rather use a method that works than a "correct" tech-
nique that I never quite mastered — especially since I'm con-
stantly switching between two computers on one side of the
room and a typewriter on the other.)

The Premium keyboard does have an excellent feel. The
ads say that it is an ALPS keyboard (ALPS makes the
keyboards in the Model III, the Model 4 and the Commo-
dore 64). but the unit I received was made by Oak. which is
better known for cable TV converters and the ON TV pay
service. It is, however, very much like an ALPS keyboard
except that Micronix has wisely avoided the stampede
toward "sculptured" keys in favor of the more normal stair-
step layout. A problem with the Oak keys is a tendency for
the space bar to come back up slowly after it is pressed; the
bar doesn't actually stick, but it is difficult to type a string of
spaces quickly.

The Versakey keyboard driver program, which is supplied
with the Premium and Professional keyboards, works on
I6K. 32K and 64K. systems. It apparently doesn't require
Extended Color BASIC (although I did not try it on the 8K.
Color BASK"), and it can be easily backed up and transferred
to disk. Versakey lets you redefine any key combination to
represent any desired string, so you can set up the keyboard
to let you use single-key commands for basic statements.
You also get a repeal feature, and the cursor is now a
blinking black block instead of a multicolored one. The 64 K.
version has a bug that causes the system to crash when you
press the [Reset] button; on all size systems, you can't save
your redefined key codes, despite the instructions in the
manual.

Because of the Premium keyboard's minor problems, I
would suggest that you look carefully at it and the other
upgrade keyboards on the market before making yourchoice.
It is not only usable but useful, and it will give good service
reliably, but you may like another keyboard better.

A Colorful, Large-Character
Generator For The CGP-115

Programs written to exploit the capabilities of the CGP-
115 plotter are so few there is a distinct temptation to
overrate those that exist. Firms like Custom Software Engi-
neering have made the deliberate decision not to adapt their
Graphic Screen Prim Routine for the little printer-plotter,
for reasons sound enough in their eyes; and this decision has
had the merit of opening the field for smaller and hungrier
firms.

All-American Ultralight Industries seem to be a very
small firm (their documentation is run off on a copying
machine from a typewritten original, for one indication),
but they have already scored one remarkable success with
CPP (Color Picture Plotter), for four-color screen dumps of
PMODE 3 screens. Banners Banners Banners again addres-
ses the CGP-1 15 market, this lime to generate banners of up
to 250 characters in any color or a II four, in 39 sizes from 25
(about ' i the paper width) to 63 (almost the whole width).
Its method is to redraw the characters a selected number of
limes while incrementing the X and Y axis by a selected
amount between repetitions. Since that sentence may not
convey very much real information, here is an example to

The manual, two sides of a single sheet, tells you all you
need to know with perfect clarity. Its most refreshing
moment comes early, when it advises you to run the pro-
gram first and then read the instructions and follows this
advice with instructions on how to run the program.

The author. I..W. Beears. is undoubtedly one of those
programmers who have been attracted to CoCo from the
SS-50 bus by the possibility of actually making a living
programming for the larger customer-base. They are a
remarkably skillful lot. and a welcome addition to our
resources, but you can tell them fairly easily by certain
distinguishing traits. Mr. Beears uses Sugar Software's
Auto-Run module which employs many ROM calls, but his
own machine-code, in CPP, employs none: Rich Parry, who
gave us The Composer, seems to think in 6800 code, as may
be seen from the sound effects routine he included in that
package. These are not faults, mind you.

Banners Banners Banners was written entirely in Extended
Color basic, for case in altering input parameters. No. that
does not make the program run intolerably slowly, the
CGP-l 15 would lake the same lime if written to in C. PL/9
or 680° machine code. But it does make the misspellings in
the screen display a lot easier to correct ("repetitions" is
spelled "repitions". for one example).

I would like to report that this is the ultimate banner
generator for this printer. It is not. The fault is not Mr.
Beears'. however, except that he has made use of the CGP's
built-in character set, which produces characters not very
attractive at best. What he now needs to do is supplement
this program with one which will furnish custom character
sets, perhaps several of them, for selection by the user.

Time Patrol— A Fun Way
To Spend Some Time

Time Patrol, by Computerwarc, is a grcal 32K graphics
game for all space shooter fans. In this intergalactic Adven-
ture, your ship is at the center of a moving cosmic screen
display. You arc attacked by swarms of the enemy and must
defend yourself with twin rapid fire cannons. The enemy
first appears in biplanes with a dirigible as a mother ship.
When you manage to shoot the mother ship, you are
advanced to another level with a different style of enemy
craft attacking and a more advanced form of mother ship to
destroy.

The game has both a practice mode, with 255 planes
available, and a play mode, with four planes available and
extras awarded every time you advance to the next level. In
the play mode, the top 10 high scores are displayed between
games. This assures bragging rights for all the sharpshooters
in the family.

Graphics and sound in this game are well done. The
graphics arc quite detailed and smoothly animated for good
play value. False or aliased colors are used and you may
press the reset button until you get the color (red or blue)
that you prefer. The sound effects used arc not spectacular,
but they work well with this game. The gun sounds, in
particular, are quite effective in conveying the effect of a
heavy rapid fire weapon. One joystick is required and joy-
stick response is quite good using the standard Radio Shack
joystick.

The game is supplied on an autoloading tape in Compu-
terwarc 's attractive hanging package. The documentation
describes how to load the game by typing CLOADM. the
basics of how to play the game, one good hint, and instruc-
tions on how to get a damaged tape repaired by Computer-
ware. Since this is a copy-protected tape, this is a necessary
option even at the price of $5 for tape and $8 for disks.

In summary. I feel this is a well-done game with good
graphics and worth the time it takes to load the tape.

Great Fun For
Beginning Adventurers

The first thing that really impressed me with Owl's Nest's
Adventure Starter Package was the documentation. While
only two pages long, these instructions to the beginning
Adventurer are excellent. The explicit information not only
goes into how to load the programs, but provides detailed
hints and ideas about the Adventure games, lithe info sheet
is not enough, the first Adventure, MYHOUSE, includes a
"HELP" command that encourages you to try something
you may not have done.

MYHOUSE has you entera house, find a gold coin, and
escape from the house. As simple as this sounds, it actually is
an interesting game. You are required to get into the house
and then roam through it. trying to find the combinaton to
the hidden safe. Now, I do not claim to be a fantastic
Adventure player: suffice it to say that it took me twice as
long to finish the Adventure (about a half-hour), than my
children. And it certainly did not help when my youngest
son thought it was really funny that 1 was trying the wrong
safe combination. They felt the Adventure was a snap and
really enjoyed it. I enjoyed it. too.

The directions for loading require you to PCLEARO
(POKE 25.6:NEW) but did not mention that you should
also remove the disk controller pack.

When you have mastered MYHOUSE. Owl's Nest Soft-
ware includes a second program. PIRATE ADVENTURE.
This is a litte more difficult to complete and 1 found that it is
quite easy to lose by swimming in the ocean and being eaten
by a great white shark (not a nice way to go) or by falling into
a pit with no hope of escape (better than being eaten by a
shark). PIRATE ADVENTURE has you find the treasure
and does become more complicated by requiring you to do
things like finding the oars to the rowboal before being able
to row.

Both programs do a nice job ofdeveloping an interest in
Adventure game playing and were enjoyable. Now, excuse
me while 1 try to swim away from that shark again.

Euchre — An Entertaining
Card Game Of Tricks

Card games have always been a favorite of mine, espe-
cially if they require skill as well as a little luck to win. If you
win then you can compliment yourself on your high degree
of proficiency, and if you lose. well, you can always blame
lady luck for having turned her back to you.

Having written the pro-gambler oriented program Black-
jack Royale for the CoCo. I have a pretty good idea just how
difficult and time consuming it is to develop a program that
accurately simulates a simple card game. For the author it
usually is a labor of love rather than a profit making vehicle,
and for the end user it is a dream come true that someone
took the time to do it. Many times while reviewing this
program I had flashbacks to the time 1 was developing and
debugging Blackjack Royale — the ever-perking coffee pot,
overflowing ashtrays, gallons of midnight oil and the com-
plaints from others that I was spending too much time
hacking away! It is hard not to feel a kinship towards the
author of this program I am reviewing.

Euchre is a perfect example of a card game that can be
converted to run on a computer to entertain and challenge.
During the late 19th and early 20th century. Euchre (pro-
nounced "You-ker") was the most popular card game in the
United States because of its simplicity and fast play. Since
most variations of the game require at least four players, it
lends itself well to family play, a fact which must have
contributed to its widespread popularity. Many versions
exist that were transplanted from England, France, Ireland

and Germany with this adaptation most closely resembling
the version called "Hasenpfeffer" developed by the Pennsyl-
vania Dutch, although it does not exactly match any varia-
tion listed in the rule book of games "according to Hoyle."
The game of Euchre can best be described as a game of war
with many subtleties and fine points to make it more inter-
esting and challenging.

This 32K version is written in BASIC using PMODE 3
graphics and is available on cassette or disk. The program is
not copy protected; in fact, the manual advises the user to
make backup copies just in case the glitch fairy steps on your
master copy. (My word, not theirs!)

After loading and running the program you arc prompted
to press the reset button until the letters on the screen arc
switched from blue to red at which time you are ready to
play. There are four players grouped in two teams of two.
although only one human player can participate. The other
three positions, including that of your partner, are played by
the computer. You may select to play without a partner, in
which case you arc pitted against the opposing team of two
players.

The deck is a standard poker deck using only the 9. 10.
ace. king, queen and jack cards of all four suits, for a total of
24 cards. Each player is dealt five cards with only your hand
face up. The top card from the remaining deck is placed face
up as a proposed trump suit that players have a choice of
accepting or rejecting. The players, in rotation, place one
card from their hand in the center after establishing the suit
for that round of play. The team with the highest card value
gels the "trick" and the point for thai round of play. Alter
five rounds of play the team with the highest number of
tricks gets the point for that hand. New rounds of play are
completed until one team scores a total of lOand is declared
the winner.

The graphics are quite good with the card faces very
similar in design to the video card gambling machines found
in Nevada casinos. Sound effects are used very sparingly,
but with good effect, as a beep is heard when each card is
dealt or played. This seems sufficient without being distract-
ing to the player.

The documentation is poor in both content and quality,
consisting of four pages faintly painted on one side only,
with a line width of about 50 characters. A description of the
rules and play of the game is given in detail using terms such
as left and right Bauer-Jack, trump suit and trick. Inex-
perienced card players may be unfamiliar with these terms
and may have to refer to a book on card games to compre-
hend them as they are essential in understanding the hie-
rarchy of card values.

In two ways Euchre could be considered a "classic." It is
an excellent, well-written and entertaining program that
plays well and shows what can be done with graphic com-
mands, well-designed screen formatting and tightly-struc-
tured programming. In quite another sense it is a classic
example of a good program being weakened by poor docu-
mentation, which assumes prior knowledge of the game.

All things considered, however, I would recommend
Euchre to anyone who likes to spend cold winter nights
playing card games against the computer. Card game

Pager/ 64K Boot—
Two More Utilities For CoCo

Skyline Software has come up with two utility programs
that are for 64K CoCo owners only. If you don"t have 64K.
read this review anyway; it will give you a sampling of just
what you are missing!

The first program. Pager, makes use of the 68()9's ability
to select separate 32K banks or pages of memory. To load.
first clear some string space and reserve a spot in upper
memory for the program. The normal CLOADM and
EXEC commands start the program. At this point you are
presented with a menu of five options to choose from and
also what page you have selected. Page or Page I . The first
option duplicates the menu and switches you to Page I or
vice versa if you are already in Page I. Option two allows
you to copy a BASIC program from the present page to the
other page. Number three will copy a specified area of RAM
from the present page to the other, you supply hex start and
end addresses for this step. Option four will swap the entire
contents of each page with each other from 0000 up to the
area you protected before loading. Finally, choice five lets

you get back to BASIC. Anytime you want to jump back into
the program just FA" EC and you will be back in the menu
mode.

Besides demonstrating some unique features of the 6809
CPU. you may be asking yourself, "can this program do
anything useful?" Probably the most common usage will be
in modifying or editing an existing BASIC program. Your
original program can reside in Page and the modified one
in Page I. This way any changes in program operation can
be checked just by changing between pages and comparing
their operation with one another. If your modified program
crashes you have a "backup" on Page to save you. Or. let's
say you are ready to CSA VEyova favorite many line pro-
gram; just copy it into both pages and CSA VE to tape. If
you cannot CZ.0/4Dduetoa bad tape or whatever, you still
have a "backup" on Page I to try again with.

The second program supplied is 64 K Boot. This enables
you to copy the material in ROM to RAM and puts the
CoCo into the 64K mode. The main advantage in having
ROM in RAM is the ability to modify basic. This requires a
knowledge of the basic memory map so you can poke in
various changes such as Baud rate or even the stepping rate
of a disk drive.

The documentation is brief but more than enough to get
started. Also included is the assembler source code for both
programs a treat for ML buffs.

The Complete Personal

Accountant — An Excellent

Financial Package

The Complete Personal Accountant is an excellent piece
of software that has been developed for the Color Compu-
ter. This package seems to be able to produce all the infor-
mation that an individual would need to know about his
financial health. I'm sure that would apply to a small busi-
ness also. To use CPA , you will need a Color Computer with
Extended BASIC and either one disk drive or a cassette
recorder. There are two versions. I6K and 32K. (If you
purchase the 16K version for disk, you must store some data
on cassette because of memory constraints.) It is not neces-
sary to have a printer but, I personally wouldn't want to use
a program of this quality without one.

I'm not going to be able to cover all the bells and whistles
of this package, but I will cover the main features and
describe the function of each of CPA 's ten programs. I am
reviewing the second edition of the disk version. It comes
packaged in a three ring binder with 153 pages of excellent
documentation. At first I got a little irritated at the author

because I felt the documentation had too much repetition,
but then I realized it was written this way so that once you
have initially set up your files you can utilize any of CPA s
ten programs without having to backtrack through the
manual to figure out what you are doing. The manual is
broken down into three sections and at the end of each of
these sections are some examples of what your reports
should look like. The only criticism I have of the documen-
tation is that the three ring binder has Vi" rings and this
makes it quite difficult to flip the pages without tearing.

With CPA you can: record checks and deposits; balance
your checkbook; record savings, loans and investments;
print checks; budget your spending and savings; graph
financial information; keep track of bills and appointments;
and print a mailing list. In order to do all these things, there
are ten different programs that you can call from a menu.
Many of the programs work together to give you the infor-
mation you want, but I am going to try to describe each one
separately for the purpose of this review.

Chart Of Accounts — This program allows you to establish
your own unique set of accounts (up to 99). Each account is
assigned a number from I to 99 in the following manner:
Asset Accounts (I -20), Liability Accounts (2 1 -45), Equity
Accounts (46-50), Income Accounts (5 1 -60), and Expense
Accounts (6 1 -99). An account can then have up to nine
sub-categories. For instance, if you had an expense account
set up for medical, you could then set up subcategories for
each doctor, the hospital, drugs, etc. The only limitation is
that the total number of accounts plus subcategories cannot
exceed 24 1 . Each account name can be any combination of
up to thirty letters and numbers. Each subcategory can be up
to fifteen characters long. The package comes with 66
accounts already named and numbered for you. You can
add to or change any of these if you like. Adding, changing,
or deleting an account is a breeze and as long as you use the
save option every time you make changes you will have a
current chart of accounts.

Checkbook Maintenance — This program will keep a record
of all your checks, deposits, service charges, and payments
on any of the accounts set up in your Chart of Accounts. It
will assist you in keeping track of tax deductable items and
help balance your checkbook. In addition to keeping track
of individual checks you have written, you can use CPA to
break a check down into as many as 25 separate accounts.
Let's say, for example, you use a credit card to purchase
gasoline, some clothes, concert tickets, and new software or
hardware for your Color Computer. If you pay off this bill
with one check, you could assign portions of the check to the
appropriate accounts. Balancing your checkbook is easy
with this program. Of course, if it doesn't balance you will
have to put forth a little effort to find your error, but it
should be easy if you print out the checkbook and compare
to the bank's statement. You can print a copy of your
checkbook at any time for any month. The printout will give
you the totals for deposits, checks written, and tax deducta-
ble items. If you want, CPA will even print checks foryou. I
must say though that I wasn't impressed with this feature. I
printed out some checks on regular printer paperand it used
practically the entire eight-inch width for the check. It would
have been nice if the documentation gave some hints on how
to customize this for your own checks or at least information
on where the checks the program was designed for could be
purchased. One other thing that might cause you a problem
is that the description of each check you enter is limited to

just 1 5 characters. This means that when you want to write a
check the payee's name must be limited to this same 15
characters.

Checkbook Search — This program will allow you to
search your checkbook by check number, deposit number,
description, date, or account number. For example, you
could get a printout of all the checks you wrote for food
during the year. There is also a browse option which will
print the entire checkbook on the screen or printer.

Detail Budget Analysis — This program allows you to
create a budget and compare your actual spending patterns
to your budget. At any time you can add. change, or delete a
budget record. You also have the option of searching
through your budget file forward or backward sequentially,
or look for a particular item with the search option. You
have the ability to analyze your budget to your heart's
content. If you want you can produce a report of all the
checks you wrote against each budget account. This report
can be sorted by account, subcategory, check number, date
of check, amount of check or the payee.

Summary Budget Analysis — This program will print a
summary of your budget so you can tell at a quick glance
how you arc doing compared to your budgeted amounts.
This report is actually a summary of the Detail Budget
Analysis.

Net Worth/ Income Expense — This program will keep
track of all your finances. You can print a balance sheet that
shows your assets, liabilities, and net worth. You can also
print an income; expense statement. A lot of the informa-
tion for these statements comes from the entries vou make in

your checkbook. There may be some things though that you
do not process through your regular checking account such
as the software or hardware you purchase for your computer
that you don't want your spouse to find out about. These
items can be entered into the file with a maintenance option.
You can enter information such as the outstanding mort-
gage on your home, etc. When you finally get all the neces-
sary data entered, you can print out a balance sheet to
income, expense statement that looks just as impressive as
the ones you sec in corporate annual reports, only yours
probably won't have as many trailing zeroes as theirs.

Payments Calendar — This program allows you to enter
four pieces of information about those periodic bills you
have to pay. The information is: bill name (or payee),
amount of bill, month due. and the date due. If the bill is due
every month then you can enter a special code and it will be
included in the calendar every month. Once you have all this
information entered you can get a printout showing when
each of your bills are due during the month, how much they
are for, and to whom they arc to be paid.

Appointments Calendar — This calendar is quite similar to
the payments calendar. For this one you enter three pieces of
information: appointment month, appointment day. and
appointment information (up to 24 characters). You then
have the option of getting a printout of a particular month's
appointments or you can specify to have the printout list
those appointments between any two days you select.

Mailing List — This program will allow you to establish a
mailing list and then print out the addresses on em elopes to
mailing labels. The documentation doesn't say how many
addresses you can store. This isn't as fancy as some of the
mailing list programs on the market, but it will meet the
needs of most users. Once the addresses are loaded you have
the option of changing or deleting the addresses, and of
course you can always add addresses. If you are looking for
a particular address you can search by account number,
addressee, address, city, state, or ZIP code. In regard to
printing the addresses, you must either print all addresses or
you can select one address at a time to print out. The
program is set up to print single width labels.

Color Graph — This program allows you to print graphs of
any of your financial records on the screen. The graphs are
quite impressive and will allow you yet another method of
analyzing your financial records. If you are really ambitious
you may be able to incorporate one of the screen print
programs to this one to get a print out of the graphs on your
printer.

As you can tell, I'm quite high on CPA. It is an easy
program to initially set up and use. The documentation is
written in such a manner that if you only use the program
once a month, you don't have to read the entire manual to
figure out what to do to get the information you want. You
just turn to that section of the manual and follow the instruc-
tions. Although l did mention a lew things I didn't like about
this program, they are primarily trade-offs the author had to
make because of memory limitations, etc. I certainly would
recommend this program to anyone with a need in this area.

ML Doom — A Good
Disk Based Adventure

Adventure games are nothing new on the CoCo software
scene. In fact, the first program I bought for my CoCo was
just such a game. Since then. CoCo has expanded greatly,
both in the hardware and software departments. With 32 or
64K. and a disk drive, much more sophisticated software is
possible. Fortunately for us, the CoCo software vendors
have seen fit to take advantage of these increased capabili-
ties. This applies not only to games, but to the more serious
applications as well.

Journey To Ml. Doom is a 32K disk-based graphics
Adventure. The program itself is written in basic with
machine language subroutines. The disk contains the graph-
ics for the various locations, which are loaded directly into
graphics memory as you move from one location to another.
Although this process slows the game down to a small
degree, it is much faster than having to draw the graphics on
the screen each time.

The object of the game is to prevent the "Necromancer"
from waging war on the earth. To do this, you must first find
the "magic ring." then make your way to Ml. Doom and
destroy the ring, and finally return to your starting location.
Naturally, there are many obstacles along the way. as well as
some treasures to be found. Your score, if you survive, is
based upon whether or not the ring is destroyed, and upon
the amount of treasure you can bring back with you.

Playing the game is very easy. By using one- or two-word
commands, you tell it what it is that you want to do. For

example, you can TAKE an object, LOOK at your sur-
roundings, get an INVENTORY of what you are carrying,
and move NORTH, SOUTH, EAST, or WEST. There are
other commands as well, but it is up to you to figure out
what they are.

While you are playing the game, the upper half of the
screen shows your surroundings graphically, while the bot-
tom half of the screen lets you know what is going on. The
graphics are done in PMODE 3, and are generally pretty
detailed. The text, also in PMODE 3, is also pretty good,
although 1 had some trouble distinguishing some of the
letters at first.

There is also some measure of randomness to the game.
Every once in a while, a Goblin will appear and throw a knife
at you. which may or may not be fatal. There is also a spider,
who comes along to steal one of your treasures. If these kind
of things annoy you, the odds of them happening can be
easily changed, after studying the program for a while.

Journey To Ml. Doom is a very good Adventure. The
graphics add a great deal to the enjoyment of the game, and
it is difficult enough to keep you thinking for a while (or
forever if you are as skilled at solving Adventures as 1 am).
The only thing it lacks, is a "save game in progress" feature,
which I feel should be a part of any Adventure game. The
documentation is skimpy at best, but then you should not
expect a great deal of help with this type of game. If Adven-
ture games are your thing. Journey To Ml. Doom is a
refreshing change from the "text only" variety.

Software Review!

T/7Z\

Suffering From Disklock?
Then Use Diskey!

You've heard it said before, but I'll say il again: "If you
have a disk system, then sooner or later a disk with your
favorite/most critical program will crash!" And probably
without a backup copy. So, you owe it to yourself and your
CoCo, not to mention your loved ones who hate to sec you
beating your head against the wall, to get one of the disk fix
utilities which is out on the market. I kept putting it off and
between luck and taking good care of my disk and disk
drives I didn't have much trouble. But, sure as Murphy, a
couple of weeks ago my "working-on-it" disk, with over 40
man-hours of partially completed programs, bit the big
byte. AARRRGGGHHH! I put the disk away for future
salvage and luckily for me the review assignment that I
received this time is DISKEY Disk Access anil Repair Key
from Adventure International. Serendipitous, yes'.'

1 haven't seen any of the other disk fix utilities available in
actual operation, so I can't really make any comparisons.
But I do know that DISKEY does everything their ad says,
and even has a "bonus" or two.

One thing 1 remember mentioned in a review of one of the
other programs was the learning method used was to have
you reconstruct the program disk itself, and DISKEY docs
this also. In addition, the information in the documentation
is worth at least one-third of the price by itself. The docu-
mentation was very professionally done as you might expect
from a company like Al. who has finally started supporting
the CoCo( we knew it was worth it and I think now everyone
else knows, too). It comes in a nifty 6x7 three-ring binder
which contains the disk also and has fifty pages of instruc-
tions, info, tables and charts. My only minor complaint
being that the copy quality of a couple of tables "faded" in
places probably due to being line printer output rather than
being typeset like the rest of the book.

You are given instructions on the operation of the pro-
gram first. Then there is a tutorial on just how the RS Disk
System sets up its directories files, etc. Following that arc
samples of the charts to be used when the program is run (see
listings below) and tables of very useful information. Then
there is the "walk-through" of how to recover the other two
programs on the disk. These turnout to be a BASIC program
that will act as a menu-driver for your disk allowing you to
select and execute any program on your disk. One normal
save and one in ASCII format to help you learn the differen-
ces between the two so far as recovery is concerned. There
are also samples of the printouts available from the program.

The main program is actually two programs in one: the
DISKEY section and a diagnostics section. The diagnostics
test CoCo thoroughly and almost anything else you might
have hooked up (disk. tape, printer. . .). Everything here is
pretty much self-prompting and there is a section in the back
of the book explaining all tests. Like the documentation this
section alone is worth part of the price all by itself.

The main two routines of DISKEY arc Disk Map and
Examine Edit. Disk Map draws a graphic map of the disk
being checked and color codes any sectors that have
Read Write 10 Errors so you know if your problems are
firmware related or software giltches. Then Examine Edit
allows you to check data in all sectors and directly edit
anything you find. This is where you collect the data needed
bv the Reconstruct Directory section that you learned how

to do in the "walk-through." The other routines available
are:

Erase Disk — which "zeros" a formatted disk by writing
FF hex to every byte.

Backup — which works like Basic's but keeps you
informed as it goes.

Copy — which copies by track numbers specified.

Print Directory — with a little more information.

Calibrate Drive — which is actually sort of a MOTORON
for disk allowing you to perform some of the care and
maintenance which is also outlined in the book (along
with a safely warning and the advice not to try anything if
you don't know what you are doing).

The only trouble I had with the program itself was that the
arrow key movement around the edit display was touchy as
heck and made it hard to put the cursor exactly where you
wanted without overshooting a couple of times. Also, it
would be nice if the examine section did a quick run-through
of the disk and told you which granules had active sectors in
them. You would still have to examine them "by hand." but
it would be quicker than checking each gran yourself, espe-
cially if you're not sure how full the disk is.

But. these are only nit-picky details in a very profession-
ally done program that does so much! By all means, if you
have disks and don't have a disk repair utility then DISKEY
would be an excellent choice.

Clock Drill: An
Education, Timely Tool

If you're among the fathers who, after mom has left for
work, find yourself constantly telling the youngster to get his
school clothes on, that we're running short on time, you will
appreciate Clock Drill, an educational program from CY-
BURNET-ICS of Knoxville.

Clock Drill is an autoload program requiring 32K, is
menu driven and is designed to be both student and teacher
friendly.

A large analog — you remember, the old kind, round and
two revolving hands — clock is displayed on the screen for
each problem. A seven-menu item offers the following
options:

— On the hour.

— Half hour.

— Quarter after.

— Quarter till.

— Hour, 15 after, half hour, 15 till.

— Five minutes.

— By the minute.

On each screen, the computer randomly selects the time
appropriate to the menu option. The student inputs the
answer in a digital display at the lower lefthand part of the
screen. If the selection is incorrect, a low buzz sounds indi-
cating that he or she needs to try again. At any rate, the
answer must be correct before going on to the next problem.
Get it right and there's a neat little tick-lock, tick-tock sound
for a reward.

A grandfather clock, complete with pendulum and a
selection of "Hear the Chimes Ring. "awaits the child when
he makes 12 correct answers in a row.

A nice feature, especially for those who are in the early
stages, is the presence of a help key, which, when pressed,
signals the numeral representing the correct hour on the
clock.

Pressing the spacebar once will display minutes incre-
mented by five around the clock face. A second tap erases
the display.

Included as a bonus with each program is Clock Class-
room Tutor, which the creators say has been used in the
classroom in Knox County, Tenn., for individual and large
group instruction. It allows time comparison by the clock
face, digital notation, and by spelled-out versions. It also
includes placement and significance of the minute hand, and
increasing difficulty as the program progresses.

For teachers in the lower grades who have had difficulty
in locating good educational programs to go with those
new-fangled computers that the board of education has
placed in their classrooms. Clock Drill is for you.

Order Entry System
Provides Sales Help

Order Entry System is a neat little package that a small
business could use to print invoices and keep track of sales.
To use this program, you need at least a 32K Color Compu-
ter with one disk drive, and an 80-column printer. The
documentation also says you need the Mark Data Products
Super Screen program which is included on the disk. The
Order Entry System is actually a combination of several
programs that are menu driven.

In order to tailor the program to your specific needs, you
will have to delete some data statements that are used for the
demonstration program and include some of your own. You
may also need to make some other changes to make the
program compatible with your printer. This is really no
problem, though, as the instructions are written quite well.

With Order Entry System, you will be able to print:
Invoices. Sales Reports (either daily, monthly, or for any
other period), and a Receivables Report. Creating, modify-
ing, updatingand maintainingthedata files isquiteeasy. As
I mentioned earlier, there is a demonstration program used
as a tutorial that will have you capable of operating and
understanding the system within one hour. The documenta-
tion (23 pages) is written quite well. There was one place,
however, where the documentation could have been a little
more clear; that is in the tutorial section on reviewing
records. The tutorial tells you to type in the record number
you want to review. The only problem is, you don't know
how many records there are yet unless you are very percep-
tive and noticed it on the screen. Anyway, as long as you
press the number 12 or less you will be okay.

The heart of the Order Entry System is the SA LES. BAS
program. This is where you actually enter your sales orders
and prepare the invoices for shipment. With a single disk
system you can enter up to 488 transactions and, with two
drives, you can store over 600 transactions.

Hints . . .

Color Computer 2 Warning

If you are upgrading your new CoCo 2 to 64K, remember
that the 1 6K chips you are taking out are not the same as the
16K chips (type 41 1 6) that earlier CoCos used: they are type
21 18, which usea different power supply (+5 voltsonly)and
will not work in earlier units, and could cause damage. (If
you intend to do a 32K "piggyback" expansion on your
CoCo 2, use another set of 2 1 1 8s, not 4 1 1 6s that came out of
an older computer.)

A sales order is either closed (cash, check, money order,
credit card) or open (C.O.D. or open account). As you enter
each order it is placed in the appropriate open or closed file
and a multiple copy invoice is prepared. (The documenta-
tion does include a sample of the type of invoice the program
is written for.)

When you receive payment for an order that is on open
account or a C.O.D. you can credit the account by selecting
the "close and open order option." To enter a sales order,
you will be asked to input the following information: Ship
To, Bill To, Purchase Order Number, Method of Shipment,
Terms of Sale, and various Product and Discount Informa-
tion. You do have the option of combining sales of products
that have different discounts on a single invoice. You also
have the option of adding tax, C.O.D.. and handling charges
to the invoice.

The other options of Order Entry System allow you to
print out reports of closed orders (sales) and reports of open
orders (receivables). The report of closed orders will print
out the following information for each order: invoice
number, date of transaction, terms of sale, net sale, tax,
shipping charges, C.O.D. charges, and the total sale price.
Once this information is printed out you will get another
report which gives you a sales breakdown. The sales break-
down will tell you how many of each item you have sold and
the total amount of revenue each item has produced. This
report will also tell you how much of your total receipts was
Cash/ Money orders. Checks, or Credit cards. The report of
open orders will print out the same reports but will be for
invoices you haven't received money for yet. The reports can
be requested for a single day or the entire month.

In general, I feel this is a good program that would serve
the invoicing needs of a small company quite nicely. There
are a couple of items, though, that are quite inconvenient
and may cause you some concern. When entering informa-
tion for the invoice, if you realize you made a mistake a
couple of lines above, you must use the [up arrow] to get to
that line. This would be no problem except that it wipes out
all the information between your current line and the one
you are going to. It would have been nice if the program had
a feature that allowed you to select the line number that
needed correcting like many other data entry programs do.

There was one other problem that I ran into in entering
information for the invoice. When entering the "Bill To:"
information you can type the word "SAME" if it is the same
as the "Ship To:" information. The program will then auto-
matically skip the rest of the "Bill To: "section so you don't
have to enter the information twice. This works fine unless
you are using the lowercase mode, in which case, the pro-
gram doesn't recognize the lowercase "same. "This problem
also cropped up when 1 attempted to enter additional items
for the invoice. As you complete an item on the invoice, you
are asked if you want to add another item. If you do, you are
to respond with an [N] which represents "NEXT." If you are
in lowercase and respond with an [n], the program does not
allow you to continue as you intended. These are not that big
of a deal, but if you buy the program, you should at least be
aware of them.

If you are looking for a program to keep track of your
sales and print invoices, then this one will take care of these
needs quite well.

Cashman: A Fun Investment

One of the main reasons 1 bought a CoCo was to play
colorful arcade games, so I'm always glad to gel the oppor-
tunity to review one. 1 did, however, experience one very
small problem in reviewing Cashman, which I'll tell you
about shortly.

But first, let me tell you about the game. Cashman is a 32K
self-starting, machine-language game from Computer Shack,
available on disk or cassette. Although it may appear to bear
some superficial resemblance to Canyon Climber or Don-
key Kong, it is totally unique.

One thing that makes it quite different from any other
video games I have ever seen is the fact that, when two
players arc competing, they do not just alternate taking
turns. They actually play together on the same screen, vying
for treasure and hurling eggs at each other. (Hurling eggs?
That's another unique feature!)

There are more than 40 screens. The instructions do not
specify how many more, but since "experts" may begin
playing on screen 40 if they wish, I wouldn't be surprised if
there are more than 50!

1 n a two-player game, one player uses the left joystick to
move a character called the "Sheik," and the other player
uses the right stick to control the "Sailor." In a one-player
game, you can pick either one. Although the Sheik has a
blue hat and orange shoes, and the Sailor has a white hat and
blue shoes, these distinguishing features are very small, and
while playing the game with my wife, I occasionally found

myself trying to move the wrong character after they crossed
paths on the screen.

The object of the game is to clear the screen of S50 bills,
represented by dollar signs. You move horizontally along
"girders," or vertically up or down ladders or ropes, called
"climbers." Jumping is accomplished by pressing the fire
button. Unlike some other well-known climbing games,
there's no penalty for taking a fall. (In fact, on some screens,
the only way to collect a dollar sign suspended in mid-air
seems to be to fall through it.) When you collect all the
money on one screen, you're automatically advanced to the
next one.

Along the way you may find some "conveyors," which are
a sort of moving sidewalk, and "(lingers" — little trampo-
lines that will give your jumping and extra boost. But watch
out: Don't step on a "zapper" — that will cost you one of
your 10 game lives. The easiest screens have no zappers at
all. while the "experienced" and "expert" screens have
several.

Other critters you'll meet during your treasure hunt are
"Bombs," "Eggs," "Kats," and "Byrds."(The last two bear
an amazing resemblance to cats and birds.) A Bomb will
turn into an Egg or a Kat after a while, unless you grab it first
(which scores $30 for you). If you get hold of an Egg, you can
throw it at your opponent (costing him one game life), a Kat
(good for $150), or a Byrd ($250!). If you don't grab an egg.
it will soon hatch into a Byrd.

Run away from Kats. Contact with one costs you a game
life. I he Byrdscan be helpful. If you let one grab you, it will
lift you up to a higher elevation. On some of the "no jumping
allowed" screens, that seems to be the only way to get up
there. Of course, there's always the danger that it will drop
you off light in the path of a Kat.

The screens are divided into six "areas. "The first four are
"easy." The next six are "super jump." As the name implies,
all the jumps are much higher. There are 12 "moderate," five
"no jumping allowed," and 12 "experienced "screens. Alter
all that comes the "expert" area which begins with number
40. You may choose to start at number I. or you may start to
play at the beginning ol any of the areas. That way. the great
players can go directly to a level that challenges them, while
novices like me can at least get a look at what the higher
levels involve.

I here is a scoreboaid that keeps track of six high scores
—but your first six games won't automatically earn a place
on it. Arbitrary scores have been assigned to six characters
with funnj nicknames, and you'll have to beat at least one of
I hose to earn the right to enter your name.

1 here's even an alternate color set. The normal colors are
orange blue and white on a dark background with a white
border, but by depressing the spacebar at the start of each
game, you can shilt to pink and green graphics on a white
background. I found this alternative color set a bit fuzzy and
hard to play with, but I suspect that that is probably the fault
of my very old color TV rather than the program.

The instructions are well-written and easy to understand.
Although it may sound complicated, once you start playing
you'll find it very easy to gel into.

As 1 mentioned earlier, I had one small problem in Hying
to review Cashman: I found it very tough to tear myself
away from playing the game long enough to write about it!

In short. Cashman is one fun game. Buy it.

This is the finest, most comprehensive, compiele. and most truthful document you may ever find (or your microcomputer

It is an accordion-told document printed en 80*lb Beckett cover stock (or durability prepared by large-scale computer professionals who have over 20 years experience, and it is
made the way they need it lor their own usage

Each item of mlormation on the card is expressed in its simplest terms so that even the beginner can understand what is being said

The NANOS SYSTEMS CARD 15 not a tutorial, but it is not a technical document either It simply presents nearly everything you might need to know about using, operating, and
programming your microcomputer <n plain words so that you can guickly grasp every concept

NANOS SYSTEMS CARDS are used in many homes, businesses, grammar and high schools, technical schools, major colleges and universities, and. would you believe, the U S
NAVY'

NANOS SYSTEMS CARDS are not just another Quick ly-produced bunch ol publications lor the puroose ol grabbing sales while the public s still confused about the proper
literature to buy On the contrary, theyare inexpensive, and. can represent information which you might otherwise spend from twenty to one hundred dollars to get. because not
only do they summarize the manuals, but. NANOS researches each computer and inserts information not readily available anywhere else

For example one very large publisher has been marketing what they call a Quick Relerenco card It is oversize and awkward to handle and transport It contains B pages. 2 ol
which contain nothing about your computer at all 1 The other 6 pages are spread out to fill the rest ol lie card with as much as possible, with not much information II sells for 2 95
The NANOS SYSTEMS CARD lor the same microcomputer has 16 pages, all used and packed lull ol information The entire contents ol the 2 95 card above are contained in about
3 pages ol the NANOS CARD The NANOS CARD is 4 95. and. it fits in your pocket 1

Another publisher puts out a large lull-sized plastic sheet which is so technical that even NANOS himself cannot understand il all*

And finally, there are some who are publishing little mini-books and calling them Quick References The idea ol a quick relerence is lo get away Irom the book format It is*
archaic and time -consuming

The NANOS SYSTEMS CARD is the true OUlCK REFERENCE lor todays users Not only does It make an original presentation, but. it is organized so thai you can identify your

Software Review!

Key-264K - The Key To
Flexible Programming

By Donald D. Dollberg

Being somewhat of an old timer with the Color Compu-
ter, having started with a 4K Color BASIC machine over two
years ago, I've had the opportunity to watch the growing
and continuing support from third party software vendors.
I've also had the opportunity to upgrade that 4K machine to
64 K. Disk Extended BASIC with new keyboard and video
monitor. With the wave of new 64K machines, comes what I
call 64K hysteria — "What can I do with 64K?" Everyone 1
know is convinced that OS-9 is the answer. Sure, it's a great
system and adds tremendous capability (and prestige) to
CoCo. If you're into heavy programming or need to use
some heavy business type software, then OS-9 (or FLEX)
might be the answer. But, what about the casual BASIC
programmer who is happy with Color TRS-DOS? 1 believe
that Key-264K by Key Color Software is the answer.

Key-264K, by Neil Capeless comes on a cassette and
requires Extended BASIC and good 64K RAMs — the so-
called half good 64K chips which Radio Shack presumably
put into the early 32K CoCos, will not work. The program is
protected with an auto start loader and cannot be copied to
disk although it is fully compatible with Disk BASIC.
Although the program is small, 3.225K. bytes and loads
quickly, some disk users may be irritated having to resort to

tape. I spoke with Mr. Capeless about this and he assured
me that a disk version was available since January. Those
who already have the tape version may upgrade to disk fora
modest upgrade charge of $5 plus shipping. Disk versions
are available for both the 1 .0 and 1.1 Disk ROM .

In addition to the program, a 75-page manual is included.
Present software authors would do well to emulate Mr.
Capeless' documentation. This is a professional product
which is extremely well written on high quality paper and
obviously offset printed. The first 50 pages are devoted to a
tutorial or learning guide. It is designed to be used while
working with the system. Each command is fully discussed
with examples to be entered into the computer. After run-
ning each example, the command is then summarized with
reinforcement. By working through the tutorial, one devel-
ops a basic understanding of each command. But, as with
any new system, there is often the need to refer to the
manual. The last 25 pages of the documentation serve as a
reference manual. Now this is not just a list of commands
either. Each command is summarized on a separate page.
For each command, four topics are listed: command format,
purpose, comments and examples. Each page is neatly pres-
ented in outline format so it is very easy for the eye to scan
the page for the needed information.

I realize that 1 have spent a lot of time commenting on the
manual but high quality documentation takes a lot of lime
to produce and should not go unrecognized. Anyone, even
with a very elementary understanding of BASIC, will appre-
ciate the manual and find it very easy to read and understand.
Before I get into the details of this utility, I think that it
would be useful to quickly review the two memory options
available with a 64K RAM machine. On power up, the SAM
(6883 synchronous address mutiplexer) configures the sys-
tem lo the 32K ROM/32K RAM mode (memory map 0).
This is the standard 32K BASIC machine. However, if you
whisper the right bits to SAM, the BASIC ROMs will be
turned offand64K RAM is left (memory map 1). But. this
RAM is useless without an operating system such as OS-9 or
FLEX. If we want to use BASIC then we are confined to 32K
RAM — or are we?

With memory map 0, SAM can perform a function
known as page or bank selection. What this means is that
either the lower half of the 64K R AM, ie, to $7FFFcan be
assigned to BASIC or the upper half $8000 to SFFFF. With a
small operating system which can perform bank selection,
the two banks of memory can be easily accessed. Several
utilities have recently appeared which make use of the two
memory banks. However, these utilities use the upper bank
for storage of programs which can be loaded to the lower
bank or the reverse, programs in low memory saved to the
upper bank.

While this type of utility serves a useful function, particu-
larly for those without a disk system, Key-264K takes a
different approach. It provides for both independent pro-
gram operation in each bank either separately or simultane-
ously in a multi-tasking environment as well as complete
interaction between both banks such as a program in one
bank and the variables, subroutines, or extra graphics pages
in the other bank.

Let's look at Key-264K and its operation. A simple
CLOADM automatically loads the proram at the top of
32K in both banks, ie, about 29.5 K is left in either bank for
programming. Once Key-264K is installed, it immediately
does a cold start of both memory banks and adds 16 new
commands, which are listed in Table I, to BASIC. In addi-
tion, several keys are used for each side to perform such

the RAINBOW February 1984

tasks as break, warm and cold restarts, toggle Extended and
Disk BASIC, initiate multi-tasking, and duplicate one side to
another. For example, the "down arrow" key serves as the
control key for side A — the foreground side — while the
right arrow serves as the control key for side B — the
background side. Simultaneously pressing the "down arrow"
and [ENTER] switches to side B. How do you know that
you're in side B? The screen changes to the alternate text
screen, the orange screen. Pressing the right arrow [ENTER]
combination returns to side A with the original green screen.
Both sides will show the Extended or Disk BASIC logos. But,
in a disk system you can shut the Disk BASIC ROM off and
revert back to Extended BASIC — so that you can load those
"awful" machine language programs whose authors insist
on loading in the same memory location which Disk BASIC
uses for buffers and scratch pad - without removing the
Disk controller pak.

li is impossible in the space available to this review to get
completely into the details of all of the Key-264K com-
mands. Hopefully, the reader will get a good feel of the
capability of Key-264 Kby using the table of commands. I do
want to emphasize that the Key-264 K commands become a
pari of either Extended or Disk BASIC and the commands
are used in BASIC programs like any other BASIC command,
ie, no extra control keys. PRIN /"statements or whatever. In
other words, the command SWITCH is just as much a valid
BASIC command as PRINT. Of course, if you write a BASIC
program using Key-264 ^'commands, the program will pro-
duce SN errors if Key-264K is not resident in the machine.

As you can see from Table I, Key-264 K provides a
number of functions not possible in RS BASIC (why didn't
they think of these). Let's take a look at a few of these
commands. The PUSH and PULL commands are used to
"communicate" between the two memory banks. They pro-
vide a mechanism for transferring data in the form of varia-
bles between the memory banks. For example, we could
load a database program on side A and store the data on side
B. When the data is needed for the program, the command
PULL will bring data from side B to side A, e.g.. PULL
AS(25). After modifying the record we could then PUSH
A$(25) back to side B. Of course AS must be properly
dimensioned on both sides. An alternative to using a
memory bank for data storage is to use it for the storage of
subroutines. To call a subroutine on side B from the main
program on side A, the SWITCH statement is used. At the
point in the main program where one would usually place a
GOSU B statement, simply place a S W ITC H statement, e.g.,
SWITCH 100. Execution of this statement would cause
transfer to side Band begin execution of line 100. At the end
of the subroutine instead of the usual RETURN statement
another SWITCH statement with theapproprite line number
in side A would result in a switch back to side A.

Another very useful command is VIEW which has a
number of options - too numerous to mention here. V 1 E W
allows the user to place either the text or graphics screens of
either side on the monitor. It is sort of a super SCREEN
command in that it can be executed in direct mode to place a
graphics screen on the monitor. For example, VIEWAG
causes the graphics screen on side A to be placed on the
monitor. To do this with SCREEN you would need the
following code:

10 SCREEN 1.0
20 GOTO 20

As you can see, VIEW is a lot easier. To look at the
graphics screen on side B. simply use VIEWBG. The VIEW

command is not limited to graphics screens either. VIEW AT
places the standard text screen of side A on the monitor
while VIEWBT places the B side text screen, ith the VIEW
command you can monitor what is happening on cither side
without switching sides.

The combination of VIEW with the two block memory
move commands (MCOPY and CMCOPY) allows a pro-
grammer to use up to six graphics screens, e.g., the standard
two on side A and storage of four additional screens on side
B. The following brief code illustrates one approach:

1 GOTO 10

5 FOR 1=1 TO 5000: NEXT: RETURN
10 VlEWAG:GOSUB5

15 CMCOPYF9728, 15871 TO 3584: GOSUB5
20 MCOPY 9728, 15871 TO 3584: GOSUB5 etc.

In this example we'll start by viewing the graphic screen
on side A and moving blocks of memory which contain the
graphics to the graphics screen on side A. Subroutine 5 is a
standard pause subroutine. The CMCOPY command pro-
vides cross bank copying capability. In line 15 CMCOPY
will copy a block of memory beginning at 9728 through
1 587 1 from side B to side A and place it at 3584 which is the
start of the standard graphics screen which VIEW is pres-
ently set to. To move the current graphics screen back to
where we just copied from (side B). we could insert line 17:17
CMCOPYT 3584, 9727 TO 9728.

In line 20 we use the MCOPY command to move a
graphics screen on the same side in which our program is
running into the graphics screen which VIEW is set too. I'm
sure most of you do not intend to move graphics screens
around: however, this example serves as a good illustration
of these two powerful block memory copy commands which
serve a number of useful needs.

One of the major attractions to Key-264K is the capability
to perform multi-tasking. To my knowledge, only OS-9 has
this capability. So, just what is multi-tasking? Very simply, it
is the ability of the computer to execute several programs at
the same time. With Key-264K we can load a program into
each memory bank and run them simultaneously. As an
example. I loaded my favorite data base program into side B.
the background side, set up the report format and started
printing my report, 1 then switched to side A, the fore-
ground, entered the command MTON to initiate multi-
tasking and loaded my favorite game. I must say. it as a
strange feeling having full control of the computer which the
printer chugged away. Now for this capability something
has to give. Because CoCo must spend half its time with
bank A and half with bank B, both the game and printer
were noticeably slower. However, neither was slow enough
to be a problem. At least I got something accomplished, if
only playing u game, which 1 lost, while the printer was in
operation.

To carry this process one step further, I decided to load
my favorite word processor. Telewriter, into side B so that I
could print a long document while working on something
else. It was a great idea — while it lasted. After Telewriter
loaded — no more Key-264K. Telewriter had reconfigured
the computer to map I. I don't mean to imply a defect in
Key-264K, rather, the user should be aware that not ail
programs, particularly machine language programs, will
run with Key-264K, ie, each program will have to be tested.

While Key-264K provides additional capability for UASIC
proramming, it is also very useful for debugging BASIC
programs. Using thc[\] command you can test a small block

of code in the background or with the L.COPY command
send a copy of the program to the other side where you can
test modifications without destroying the original which is
on the other side. The LCOPY command has the same
syntax as LIST and has the same options except that it
"lists" BASIC lines to the opposite side.

With these few examples I have discussed and tabled, you
should have reached the same conclusion that I have. Key-
264 K is an excellent utility which adds additional flexibility
to BASIC programming. The program can best be described
as an extension to BASIC. Just as most of you have added
Extended and Disk BASIC to Color BASIC, so some of you
may wish to add Key-264-K. I highly recommend it.

Rubiconll — Patton
Would Have Loved It

1 have been a games player for many years. I play every-
thing from chess to poker and blackjack, and all lypesofwar
games from board games to miniatures. I also have learned
to love the Color Computer for all of the great graphics
possibilities and the use of one of the best BASICS available.
The one thing that the Apple and the Atari have had over us
is the availability of true, full-featured war games. We have
come of age with Rubiconll. At last we have a game which
will actually give the feel of a real battle situation.

What do I mean by the feel of a real battle situation? A
really good war game will give you some of the fear of war.
You get to see some things about people that you may or
may not wish to know. Many people think that it is not
possible to simulate the war in a game because nobody can
get hurt. Ifthe game is good, this is not true. 1 played in a war

itary Academy. 1 was on the "US" team playing against the
"Russian" team. In most such games of modern warfare, the
object is for the "US" team to defend and have all of the
massive "Russian" team jump on them and try to dislodge
the "US" material. You get to learn what Custer must have
felt like. Knowinga little about one ofthe ••Russian" players.
I told the "US" team during the pre-game briefing a little of
how the actual Russian battle plan works. A few fast moving
units go rapidly through town trying to draw fire. If they do,
the massive Russian tanks sit off and blow the buildings
away. The way to fight this is you must sit hidden and let the
first units go through. Then you destroy the tanks at close
range when they advance.

The way it actually happened was our right flank com-
mander saw all the "Russians" in the world coming down on
him. He panicked and fired at long range at a few motorcy-
cles and armored cars. When the smoke cleared, the town
and our right Hank were no more.

The game Rubiconll has all of the feel of this. In Rubi-
conll. you play the American side and the computer plays
the German side. You must cross the Rubicon (the Rhine?)
and destroy several German cities and an airfield. The Ger-
mans are outnumbered and have several of their units under
strength. The German side, however, is hidden and you arc
not. The American side must cross the river, advance against
hidden forces, and maintain supply lines.

The game is played as a board game in Lo-Res because of
the memory requirements. There is, however, a very good
and clear map that is used. I have played the I6K version of
this game and find this one much more effective. The unit
types are indicated by logical letters indicating their type.
The computer does all of the bookkeeping for you, telling
the number of the unit, the strength, and the supply factor.
This is excellent.

Many World War II unit types are used in this game. You
have infantry units (some with mortars), heavy tank, tactical
air, recon tank, artillery, and supply units. Don't forget
these last (as I did). If your units go out of supply they
cannot move and are quickly lost. One of my losses in this
game came because I failed to protect my supply units. It
also is possible to have parachute drops of units into the
battle. For the sake of several of my units, I wish I could also
have dropped supplies. Artillery is rather powerful in this
game — possibly a little more powerful than in actual World
War II action. But one good (and frustrating) feature is that
you do not have the use of artillery any time you want it. As
in actual battle situations, it is possible for the artillery to be
involved in supporting other battles and not be available to
you when needed.

The other side of the coin to panic in a real war game
situation is the "blood lust" — the old "damn the torpedos.
full speed ahead." Many great acts of heroism and stupidity
in war(the difference between these depending on the result,
not the relative bravery) is due to this. During Rubiconll
this feeling may come at the wrong time. In the game where I
did not protect my supply lines, I was rampant to kill the evil
foe and do it now. One hidden enemy unit was bypassed and
came to light behind my lines to destroy my supply unit.
Then came the "panic" I mentioned before, as my units were
cut to pieces while out ol supply.

A true war situation combines the need for both tactics
and strategy. I might define the way I use these words.
Strategy is the combination of everything that is done before
each battle to get your side ready for the battle. Tactics is the
actual conduct of the units during the actual battle. Rubi-

264

the RAINBOW February 1984

con// has both of these aspects well employed. The tactical
problems are clear cut and the success of your separate
battles involves the movement and placement of pieces.
Your strategic problems include the need to supply units, the
use of reserves, and the object of the game itself. Remember
to read the rules. Your object is not to destroy as much of the
enemy as possible. You have specific strategic objectives in
this game and your victory score depends on how well you
achieve these goals.

The documentation of Rubicon// is much better than
average. It consists of an eight-page booklet and is done on a
reasonable printer. As with most good games, the rules are a
little complicated, so read carefully. As 1 have already
stated, if you want to win, look at the victory conditions.

In warfare, one of the basic principles is to bring maxi-
mum force to one point of conflict in order to gain an
advantage over the enemy. This is one feature that is often
missed by war game designers, especially computer war
game designers. If one unit must always face one unit and
the other units are not figured into the action, the use of the
greater force against one point in the enemy line is not felt. 1
consider it a significant flaw if two or three units cannot
jump on one enemy unit. Although you may miss the feature
in Rubicon/1 at first glance, this flaw is avoided in a rather
subtle and clever fashion. When units arc "full strength" and
able to take care of themselves, they fight one-on-one. When
several of your units become "understrength."you can move
them to one location and join them with the MERGE com-
mand. Although this is not a "perfect" solution, it is a very
good one and one that does not take much memory away
from the game.

Another nice feature of the game is the possibility to save
games during the play. This will allow you to continue the
game later or to try several solutions to a given situation.
The game takes about three and a half hours to play.

I have a few suggestions to make for the faster play of the
game. If your computer will take the high speed poke, add
POKE65495.0 to the first line. You must also add: POKE
65494,0 to line 4780 to slow the computer down for the
SA VE feature.

The cassette and the disk version are both on the tape. If
you have the disk version, save to disk and make the two
above changes. Then make and save the following program
(I called it STARTER: I/O POKE25.14: POKE3584.0:
RUN" RUB//. "This makes the proper CLEARO for disk
and allows a quick startup with just RUN"STARTER. "

There are now several ways to get 64K from the CoCo,
both using the upper RAM for data in BASIC and from
OS-9. One of the reasons for more good war games with the
Apple and Atari arc the use of 48K. I would expect the
future to bring even better war games for the CoCo. For the
present. Rubicon 1 1 is one of the best — if not i he best — war
games available for my machine.

II you think I liked this game, you are right. The game is
by Ark Royal Games. A friend of mine has corresponded
with them about one of their previous games and has found
their customer relations excellent. I suggest you get this
game and go to war against CoCo. At the low levels I can
win; at the highest levels, Palton might not be able to.

Face Maker 'Speaks'
To The Young

Face is a family game with a simple but entertaining
format. It talks! After you have loaded and executed the
program, a man's face is screened, along with the words
"eyes," "ears," "nose," "mouth," and "hair." A red cursor
passes each word. If you pressany key(including[BREAK])
when the cursor is opposite "nose." for example, you hear a
computerized voice say "nose" and get a menu of different
noses. Selecting one of these shows the face with its new
nose. This simple keyboard response makes the program
suitable for toddlers and handicapped youngsters.

My two children, ages six and three, enjoyed the game and
the novelty of hearing our CoCo speak. I felt it was a lot of
code (I2K) for five words, code that might have been used
for more features. The kids agreed. One son wanted to
change the style and color of the bow tie under the face; the
other thought "no hair" should be a choice. All the features
(except for the bow tie) are red. Better use could be made of
color — the eyes could have been blue or green, for example.

Still, we had a lot of fun "making faces." I'm a former
psychologist and family counselor, and I found that Face
lends itself beautifully to parent-child interaction. Sit your
youngsler(s) on your lap and invent your own games. Here
are some of our favorites:

• Observation skills: "Close your eyes while 1 push a key.
Okay, look — what did I change?"

• Sharing opinions: "Which one do you think is funniest?"

• Sharing feelings: "Can we make him look happy? Sad?
Angry? Surprised? (How can you tell people's feelings
from the way they look?)"

• Cooperation: "Let's take turns. But I get to do the
eyes!" (this one from my six-year-old)

• Exploration: "If I could do it fast enough, could I make
him blink his eyes?"

The program is aimed at youngsters ages one to five years
old.

The packaging is simple but adequate. I liked that because
it helps keep the price down. The documentation is also
simple, the kind of step-by-step instructions that all software
should have. Both saves loaded on the first try.

Since my computer is on loan once a week to the special
education class at the high school where I teach, I had the
group take a look at Face. Even these teen-aged videogame
sophisticates were amused. One girl made this assessment:
"My little brother would love this!"

You know. I'll bet he would.

Spelling Is D-e-1-i-c-i-o-u-s With
Cookie Monster's Letter Crunch

Big Bird. Oscar the Grouch, Cookie Monster; what do all
these names have in common'.' Stumped? Ask any little
child, or maybe not so little, and you will find out that these
are the names of characters on a very popular educational
TV series called "Sesame Street."

"Children's Computer Workshop." an activity of "Child-

has again demonstrated its expertise in children's education
by introducing a series of learning programs for the CoCo!

One of these programs is entitled Cookie Monster's Letter
Crunch. The 16-page documentation that accompanies this
I6K ECB cassette program is excellent. It begins by
instructing you how to set up your computer, and success-
fully load in the program. This part may seem "old hat" to
some of you. but this just demonstrates the care that was
taken in writing the manual. The object of these games, or I
should say eductional activities, is to match up letters or
words. By doing this correctly, you proceed to bake the
letter or word in an oven that transforms it into Cookie

Monster's favorite food . . . cookies, of course!

After a well-done graphics screen is displayed, the first
menu appears. On this menu you have four main activities to
choose from. After you choose, the next screen offers you
the choice of using a predetermined word list or the option
to create your own. The next menu is the skill level at which
you wish to play. There are six levels of increasing difficulty.
Choosing a level above two will display words instead of
letters in the oven. The four main selections include a
matching activity, a matching and memory activity, a timed
matching game, and a timed memory and match game.
Pressing the [CLEAR] key at any time will end the present
activity and return you to the main menu.

It is recommended that you start with the first one.
"EASY BAKE," the matching activity, and at the first level
of difficulty. The object of this activity is to match the letter
that appears in the baking oven at the top of the screen, to
the correct letter appearing on the bottom of the screen. You
do this by means of the joystick. By moving the joystick left
or right, you will also be moving the Cookie Monster. You
must move him over the letter that you think matches the
letter that is in the oven. After you make your selection,
press the joystick button. If you are correct the letter drops
down into a tube that carries the letter to the oven for
baking. As it bakes, the Cookie Monster rushes over to the
oven, jumping up and down in anticipation, waiting for his
reward. Altera brief moment, a cookie drops down from the
oven into the eagerly waiting hands of the Cookie Monster.
He then hastily eats the cookie. A wrong answer simply
returns a tone and then proceeds to give you another try.

The next activity is "BAKE AWAY," which is essentially
the same as "EASY BAKE" except that the letter or word
that appears in the oven for you to match only stays visible
for a brief moment before it disappears. You have to
remember what was in the oven; however, pressing the
spacebar will allow the letter or word to be displayed again.

"CHIP CHASE." the third activity, again is essentially
the same as the others, except that the letters, which appear
on the bottom of the screen under the Cookie Monster, are
now moving around. You have to be quick to match the
correct letter. A timer is also added in to pace this activity.

The last entry is entitled "CHI PS A WAY. "This activity is
similar to CHIP CHASE; however, this time you really have
to keep your eyes open. The letter or word in the oven -the
one you have to match— will disappear as in "BAKE
AWAY," but the letters below Cookie Monster are moving
around, loo. Add back the timer, and you really have to
keep on your toes.

Throughout the documentation there are numerous sug-
gested guidelines that will assist you in getting the most
benefits from these programs. Also included, in the last
pages, are suggested activities you can play with this scries of
programs. Alter introducting this program to my children,
ages 6, 5. 3 and I . I have found it very difficult to try to turn
on the TV without hearing a request to play "The Cookie
Monster Game." Knowing the reputation that the Child-
ren's Television Workshop has attained. I would not
hesitate to recommend this program to those who have
small children in their home. At $19.95, it's a real bargain.

Well-Conceived Kron
Rates With The Best'

If you enjoyed the Walt Disney production of "Tron" and

you have played the arcade version of the same movie, you
will undoubtedly appreciate Kron, a new rapid-paced, high
resolution game by Oregon Color Computer Products.

You recall that in the movie, our hero becomes trapped
inside of a computer game, and for the next hour or so. he is
challenged by every conceivable video game effect as he tries
to make it back to the real world.

You know you have something special as the cover screen
is unveiled, allowing you four optional screens of play — the
silo, the spiders, the cycles and the tanks.

On the silo screen, you are trapped inside of a, yes, silo.
High above, three levels of multi-colored blocks are slowly
descending toward you. Using your joystick, you maneuver
our hero into position to blast the blocks before they flatten
him. You may aim in three different directions, but don't get
too close because their touch is fatal. And don't brush up
against the side of the silo, either.

The spider screen is just as challenging, featuring a couple
of dozen of those eight-legged insects who are inching your
way. multiplying along the way. If you arc fortunate enough
to rid the area of them, you must make your way into the
blinking white square at the top of the screen. Careful,

though, because the entrance is small and you must plan
your move carefully.

Your entrance onto the cycles screen is preceded by realis-
tic revving sounds. You've seen this screen before if you have
typed in ihe Rainbow's listings faithfully during the past
couple of years. It consists of moving lines — yours and the
computer's. You must outlast the computer in order to
survive. Although this screen is simply conceived, it also is
one of the more difficult.

If you survived this far, you're ready for the tank battle.
Your tank is pitted against one driven by the computer. You
must travel through a maze attempting to blow up the
enemy. Careful, though, your bullets can bounce off of walls
and you can shoot yourself. This allows you to shoot around
corners, which in itself is fun. Head-on confrontations can
be dangerous because the enemy's fire power obviously is
stronger than yours. This is a fun screen and I've seen entire
games devised around the concept.

A free turn is received for every 10,000 points. When an
enemy is defeated, the screen does not reappear until the rest
of the enemies have been conquered. After you've survived
lour screens, the screen select symbols reappear and the level
of difficulty increases.

A pause feature is activated by pressing any key during the
symbol-select phase. You may resume play the same way.

I found the high score feature a little annoying at first
because, for at least your first five times through, you will
have a new high score. I just started pushing buttons altera
while, not worrying about correct initials. It would be a lot
nicer if a high score challenge were built in — to heighten the
sense of accomplishment. This really was my only problem
with the game.

Kron is written in machine language and requires 32K.

As far as graphics, sound and challenge are concerned,
this game rates with the best of them. My advice to Oregon
Color Computer Systems would be lo promote this gem a
little harder because there's a good market for such well-
conceived games.

Gorilla Banana GX-100 Printer:
Both A Beauty And A Beast

By Ed Ellers

Why anybody would want to call a printer a "Gorilla
Banana" is beyond me. Leading Edge Products, which dis-
tributes the Banana in this country, also markets a Gorilla
1 2" green-screen monitor and Elephant diskettes; they must
like animal names (which makes me wonder what they
would do if they introduced a personal computer). Once you
get past the distinctive (to say the least) name, you'll find
that the Gorilla Banana is a very economical printer for the
CoCo.

The one thing that hinders the use of the Banana with the
Color Computer and the MC-10 is its use of a Centronics-
type parallel interface. To get it hooked up to the CoCo's
serial I/O jack (where the printer is normally connected),
you must use a serial-to-parallel interface unit. A number of
these are available; I used a Botek Instruments CCP-1,
which Spectrum Projects sells for the Banana. The CCP-I's
instruction sheet tells you how to change the CoCo's "Baud
rate" (the rate at which it sends characters to the printer) to a
number of values ranging up to 9600 Baud ( 16 times as fast
as the CoCo's normal 600 Baud and approaching the speed
of a parallel interface). You then set the Botek's selector
switch to match whatever rate you chose. (As supplied by
Spectrum, the CCP-1 takes its power from the printer and
docs not have to be plugged into an AC outlet. If you
purchase directly from Botek, the interface comes with an
AC adapter which you may remove, if desired. Instructions
are provided.)

The printer I received for review was not labeled "Gorilla
Banana." It was identified simply as the "GX-100" both on
the unit and in the manual. The only clue to its source was
that it was labeled on the rear panel as the Leading Edge
Products GX-100. I've seen this printer in local stores as
well, so I think that Leading Edge was shipping the GX-
100's while waiting for their customized Gorilla Banana
units to come through. The printers are identical except for
the color of the case; the top half of the GX-100'scase is an
off-white that matches the newer "fawn gray" CoCos (the
bottom is dark brown) while the Gorilla Banana is dark
green.

The Gorilla was originally assigned for review to a Rain-
bow staff member who is a newcomer to computers. She got
the printer hooked up to her home CoCo quickly, put in the
ribbon, set up the tractors and inserted some paper. The first
line she printed turned out fine; but when she tried to print
another line, it ended up right on top of the first. (Editor's
Note: This unsettling experience happens to many CoCo
owners with printers of various brands when they first try
them out. The problem relates to the CoCo's use of serial
I/O since printers are usually set at the factory for use with
some other computers. It is not a defect. Read on.) She
frantically looked through the manual to find out what was
wrong, but could find no answer other than that the paper
might have jammed (which it hadn't). Fearing that she had
either damaged the printer or that she might wreck it trying
to get it going, she brought the Gorilla back to the office; 1
was then assigned to review it.

When I hooked it up, I got exactly the same results that
she did. At first 1 thought that the printer was defective; then
I went through the manual looking for the switch setting
instructions. On Page 11,1 found the following:

"The Printer has a Printed Circuit Board ( PCB) on
which a dip switch is located. With turning No. 3 of the
dip switch ON or OFF, the meaning of CR (0D) can be
changed to either NL (0A) or DC4 (14) respectively.
The dip switch is at the top center of the PCB. . .and it
can be seen from the back of the printer after removing
the five screws and the upper" case. NOTE: Four
switches are set to the "OFF" side when shipped from
the factory."

From my electronics experience, 1 knew what a DIP
switch was, and I knew that the CoCo expects the printer to
automatically advance the paper after each line (it sends a
carriage return but not a line feed), so I was able to set the
Gorilla to match the CoCo's "protocol" (the set of control
codes it uses). Since the manual is of little help in this
situation, I'll give the procedure here: Before you plug the
printer into an outlet, remove the top half of the case (three
screws are under the front edge, and the other two are on the
back of the unit). The DIP switch is actually four tiny white
slide switches in a black housing on the circuit board, and
the switches are marked 1 through 4. Flip switch 3 on (up)
and make sure that the other three switches are off (down),
then put the top back on.

The manual is the only thing I dislike about the Gorilla
Banana, because it's apparently written for an engineer to
use when de'signinga system that is to use the printer. It gives
you all the little details about signal levels and timing (you
are told for example that "Bringing the TEST* line 'LOW
starts the self-test printing which continues until it is
returned 'HIGH'."), but falls flat on its face when it comes to
explaining how to make the printer work with your compu-
ter. (Leading Edge told me that they have not rewritten the
manual; I think that they would do well to consider it.)

The Banana's print quality is quite good, even though it
uses a rather small (5 x 7) dot matrix rather than the 7 x 9
used by many printers. Here's what it looks like:

T r"i 1 :=• 1 :=. W h a t t h 6 G O r 1 1. 1. a B 3. T\ ■■>. ft A * S

Print in 9 looks like, fls you. can
see. there .are NO descenders on any
letters, so such things as "J", "P"
and "1" stick up above the rest of
the text a bit.

This print quality is good enough for casual correspon-
dence (although you might not want to use it to write to your
uncle in Peoria who hates computers), as well as school
work and even writing articles (most publications, including
the Rainbow, will accept such typing).

The Gorilla Banana also has high resolution "oil-image"
graphics capability, which lets you print individual dots in
any pattern you can program. Using a special driver pro-
gram (like Custom Software Engineering's GSPRB). you
can print out copies of the CoCo's Hi-Res graphics. The
pictures are of good quality, although the density of the dots
is slightly uneven (though not any more than I've seen in

the RAINBOW February 1984

YOUR COLOR COMPUTER JUST GOT WHEELS!

REVOLUTION!

You accelerate hard down a long straightaway,
braking heavily at the end for a hard corner.
You slice smoothly through the esses, and then
boldly keep the power on for a fast sweeper.
The Ferrari drifts dangerously near the edge,
but you make a tiny correction in the steering,
and you are through.

The finish line flashes by, and suddenly you
are in the pits. The car falls silent. You see your
lap times being held up. Your final lap was a
new lap record! At last, you permit yourself
a small smile.

You have mastered this powerful car on a
difficult track, driving with the assurance and
precision that comes only from long hours of
practice.

You are driving an authentic race car. You are
playing Revolution!

FANTASTIC ACTION

Revolution uses high resolution, machine language graphics
for action that is smooth and fast. The emphasis is on
authenticity in the control and motion of your car. As in
driving a real race car, accuracy and precision in your driving
are what counts. Frills and non-essentials have been left out.

PURE COMPETITION

Like a real race driver in practice and qualifying sessions, you
compete against the clock and against the existing lap record
for that track. Revolution records the lap records and the
name of the person who set the record, so you always know
who reigns supreme on your favorite track!

DESIGNED WITH YOU IN MIND

Revolution is menu-driven, and self explanatory. Informa-
tion screens tell you what you need to know. When you're
ready to play, a menu of the names of all your tracks is
displayed, along with the lap record for each track and the
name of the person who set that lap record. You select a track
with a single keystroke, and Revolution takes you there.

A NEW CONCEPT

Revolution is a unique game, because it allows you to create
the most important part of any race game: the track itself.

The first time you run Revolution, you will be able to choose
from several tracks and cars which are included with the
game.

But, with Revolution, this is only the beginning! You can
create as many tracks as you like. You can make each new
track as difficult or as easy as you wish. You can make easy
ones to begin with, and tougher ones as you become more
skilled. You may find creating tracks to be almost as much
fun as driving on them!

You can save your favorite tracks to run on again whenever
you wish. Revolution will automatically add these new tracks
to the menu . And you can exchange your favorite tracks with
other Revolution owners.

Be careful, though, about letting your friends play this game.
They may not want to let you have your computer back!

THE EARLY REVOLUTION

A prototype version of Revolution was published in the
September, 1982 issue of Rainbow magazine, under the
name The Track. The response to The Track has been terrific.

Revolution has all the features that have made The Track a
favorite, and Revolution's fast, high-resolution machine
language graphics are dramatically improved over the
prototype's.

REVOLUTION NOW!

The original Revolution for the TRS-80™ Color Computer
requires 32K and one disk drive. A new cassette version has
action just like the disk version, and similar track-saving
features excluding a menu of available tracks. The cassette
version will run on a 32 K Color Computer or TDP- 100. You
can upgrade to the disk version later, too, for a nominal fee.

olher printers).

Since the Gorilla Banana is touted as being almost identi-
cal to Radio Shack's Line Printer Vll and the newer DMP-
100. 1 borrowed a DMP-100 to compare the two. I found
them to be fraternal (though not identical) twins, with iden-
tical mechanisms but different electronics. (The LP Vll and
DMP-100 have a built-in serial interface for the CoCo,
which explains that change.) The Gorilla and Radio Shack
printers have the same standard text characters (with identi-
cal patterns for every character), the same double-width
mode and the same graphics characters. They use the same
ribbon (R/S 26-1424) and print at the same speed. They are
both made by Seikosha. whose sister companies manufac-
ture Epson printers and computers as well as Seiko watches.

Graphic Screen Print from Gorilla Banana.

Now for the differences. First, the Gorilla Banana's case is
heavier and more durable than the case that Radio Shack
uses. The Gorilla also has characters for the British pound
sign, the Japanese yen symbol and special German and
Swedish characters. On the other hand, the DMP-100 (but
not the Line Printer Vll) has underlining, which the Gorilla
does not have.

Although the Gorilla Banana and the Radio Shack prin-
ters are so similar in their capabilities, they use different
control codes to activate their various features! This means
that programs written to use the LP Vll/ DMP-100 special
features will have to be modified to work with the Banana.
Here are the codes (in decimal) that have been changed:

One other note for those of you with older 4K or I6K
CoCos:Thc old 1.0 version of Color BASIC (if you have I6K
RAM and Extended Color BASIC, type EXEC41 175 to find
out if you have it) uses a 7-bit printer output format, rather
than the 8-bit format used by newer machines (including all
TDP System 100 and Color Computer 2 units). To use the
Gorilla with the BotekCCP-1 interface on such a computer,
you will have to either change the jumper wire in the CCP-I
to the 7-bit position (which means that you will not be able
to use graphics) or use a driver program for all printing
including text. (Radio Shack had this driver available by
special order as 700-2013, but they may have discontinued
it.) Since you will need to change to a newer ROM if you
ever decide to upgrade to 64K, you may want to go ahead
and doit now, avoiding all that "patchwork" in the process.
(The Color BASIC 1.2 chip runs BASIC programs about 30
percent faster than the 1.0 and 1.1 versions.)

The Gorilla Banana GX-100 printer and Botek's CCP-1
interface give you a real 80-column tractor-feed printer for
about $100 less than Radio Shack's DMP-100. I recom-
mend them to anyone who wants to get a good printer for as
little cash as possible.

Fowl Play Is Fair Game

I was coming home from my local arcade still excited over
my new victories, but, as usual, I was broke. Flipping open
my mailbox, inside I found Thunder Vision's new arcade
program Jowst. I rushed upstairs and nervously loaded it.
As I waited for the 16K. 100 percent machine language
program to load. I quickly scanned the sheet of instructions.
1 could feel the arcade action pulsating through my fingers
as I slowly typed in EXEC. There it was. the flamboyant title
screen that I had just left in the arcade, now on my TV
screen. The title screen not only displays high score and the
modes of play, but it has a sparkling border and JOWST
written in flashing letters. I selected the one player mode and
that is when all the arcade excitement left me. I was in
control of a dangerous duck-fighting cantankerous chick-
ens. This just-like-the-arcade program turned out to be a
mediocre facsimile.

The documentation is typed on a small sheet of paper with
a fancy header. The documentation tells you the object of
the game, the three modes of play and gives some general
hints. The documentation is vague and it assumes that you
have a general knowledge of the arcade game Joust. The
instructions give enough information to load and play the
game, but they leave much to be desired.

The object of the game is to destroy enemy chickens by
striking them from above with your duck. One controls his
duck entirely through the keyboard and this is one of the
program's major faults. The keyboard control is erratic and
it distracts from the overall game play. The real problem
starts when a two-player mode is selected and two people
have to use the keyboard at the same time. Joystick control

would have solved this problem and it would have made
game play much smoother.

Jowst has three modes of play. They are one-player, two-
player and head-to-head. Head-to-head combat is one of the
best features of this program. This mode allows two players
to Jowst it out with no computer-controlled chickens. More
games should have a head-to-head option like the one
included in this program.

The graphics are probably not what one would see in the
arcade, but they are still good. The ducks' and chickens'
wings flap as they gracefully move across the screen. After
you hit a chicken from above, it turns into an egg that slowly
sinks to a platform. The eggs change colors just before they
hatch so you know just about how much time you have
before the egg hatches into another chicken. Even though
the graphics are good, I still lost interest in the program after
playing it a few times.

The sound, on the other hand, is definitely not what one
would hear in the arcade. It's nothing more than a few beeps
and buzzes. There is no difference in sound when you get
killed or when you kill a chicken, so it is sometimes hard to
figure out what happened. The author blames the poor
sound on a concentrated effort to make this game work on
16K computers so that it would not be necessary to purchase
any expensive upgrade kits. I find this very strange since you
could upgrade to 32K for less than the price of Jowst.

This game is fair, but it obviously does not "play just like
the arcade." In my opinion, if you have I6K this program
might be worth looking into, but if you have 32K I suggest
that you select one of the 32K Joust-like programs.

.Second Annual.

Rainbow Adventure Contest

So, you're an old hand at playing Adventures, are you? And you're confident
that you could write an Adventure that would change the entire course of
Adventure writing. Or, maybe you already have a winner that you're wanting to
share with the world — and win yourself a disk drive in the process! Here's the
chance to shine: The Second Annual Rainbow Adventure Contest.

Your Adventure can have any setting you want; itcanbe4Kto64K, Extended
basic or Color basic, machine language, too. A FLEX or OS-9 Adventure? Why
not? You've written a graphics Adventure? Great! This is a wide open contest
and the format can be as varied as your imagination. At this point, there are no
specific categories. We do promise that if you write a 4K Adventure that it will
get the special consideration due this limited format, but it's really a no-holds-
barred, give-us-your-best-shot contest — and if you're the only basic09 gra-
phics entry, why, how could we help but give you a prize? Originality counts
plenty.

Be sure to tell about your Adventure, including how to win it; it may have us stumped. Point out the salient features
of your creation and comment on any aspects that deserve the judges' attention. Put any accompanying article,
cover letter or documentation on paper and put the program itself on tape or disk. This is a must; we will not type in
even the shortest of entries. Lastly, put your name on everything and be sure and write-protect your disk or punch
out the tabs on your cassette so nothing gets accidentally erased.

Above all, get it in by May 1 , 1984, in bug-free condition complete with any necessary instructions. Keep following
the Rainbow for more details and a complete list of prizes, but remember there'll be something for everybody — for
example, every entrant will receive a free pass to the RAINBOWfest of his or her choice!

RULES: All programs must be original works, no "conversions." Entries must be poslmarked by May 1 . 1984. and become the properly ot Falsott, Inc..
publisher ot the Rainbow. Decision of the judges is final. Duplicate prizes will be awarded in the case of ties. Winning programs fo be featured in a
special Rainbow Adventure issue. Mark entries "Adventure Conlesl Editor" and send lo the Rainbow. P.O. Box 209. Prospect. KY 40059.

What Will Your Social Security
Benefits Be?

Parsons Software's FICA-83 programs will really tell
you, clearly and accurately, how much you will get when you
reach that magic age, and give it to you in hard copy if you
want to.

1 had been out of town on a long weekend, arriving back
home about 6 p.m. When I went through my mail 1 found a
FICA-83 for review. 1 usually put the cassette into the
recorder, put the program into the computer and attempt to
run the program "by the seat of my pants," but, being tired
from driving, 1 decided to read the instructions and then
look at the program the next day.

In only minutes of reading the instructions, 1 realized that
this was not the work of an amateur, but of a professional. In
my experience, fully 50 percent of all software instructions
are poorly done by people who have never had the advan-
tage of the English teacher who insisted upon "unity, coher-
ence and emphasis." Parsons Software instructions for the
use of the FICA-83 programs, however, would receive high
marks from my English composition teachers. They are
clear, concise and complete. They also tell you that the
programs are disk compatible, and they are. After reading
the instructions 1 could not wait to try the programs.

After putting the programs into my CoCo and telling
CoCo to RUN, I realized that, as good as the instructions
were, they were really not necessary. The programs are

straightforward and fully self-explanatory; asking all the
right questions and responding immediately to the answers.

There are two programs on the cassette, one(F/CA-83s)
for a quick determination of your Social Security cash enti-
tlements and printing the results to the screen, and the other
program (FICA-93P) prints out a complete summary of
your Social Security benefits using the personal data which
you have entered by answering the clear questions asked by
the program. These programs need no long study or trial
and error, but will give you what you are looking for, and in
a hurry! Both programs have incorporated the latest
changes in Social Security law and provisions for those who
continue working after retirement age.

All you have to do is, in answer to questions on the screen,
tell the computer when you were born, when you started to
work under FICA and when you plan to retire, whether or
not your salary was less than the minimum annual earnings
needed to pay the maximum FICA tax for each year and
yourestimate of COLA increases in the future. I estimated 3
percent. If you are married, you enter the birthdate of your
spouse. If you want a hard copy report, just answer that
question by entering "Y" and you get a professional looking
report.

In summary, these programs do just what the instructions
say they will do and with a minimum of effort on the part of
the operator. They are truly "user friendly." Congratula-
tions to Parsons Software!

Problems?

No, Just Pre-Solved
Situations

By D. S. Lewandowski

This month we will discuss a topic no one seems to
want to talk about. That topic is "problems." How
they are made, and avoided. First, 1 would like you to
take the correct approach in problem solving. Keep a pad of
paper, or better yet, a notebook, handy. This way, if you
encounter a problem, you can write down a specific ques-
tion, and leave enough space for an answer. This way, you
will only have to solve that problem once. There are a couple
of different methods to solve each problem. One of the best
is a Computer Club. See if someone else in the group has
already encountered your problem — why reinvent the wheel?
The second is asking the manufacturer. This method
requires "careful" documentation. Don't expect an instant
answer, most of the time the manufacturer must check with
many people to see who has encountered it. and why! To
solve a problem without documentation is completely
impossible. Don't rely on your memory, you'll end up using
phrases such as "1 think . . ..""I'm pretty sure . . .,"and so
on. Use your pad or notebook, to your best advantage.

Let's get some terms straight before we continue. The
term "source code" refers to the text we type into the editor.
It is saved to tape using the "W" command. (Example: W
TEST would save a source code file to tape using the name
TEST.) The source code can only be loaded into the editor,
and allows you to edit the file easily, and you can save a lot of
retyping if saved prior to testing the program. Then we have
"object code," which refers to the actual machine language
program. It can be loaded into the computer with the
EDTASM+ cartridge. And depending on the program, it
can operate independently. (Example: A test would save an
object code file to tape using the name test.) Finally, we have
a "ML LISTING"; this is a listing of the actual byte code of
the program, and is usually in hexidecimal. This listing
could be put in with a monitor program such as ZBUG.

The reason 1 mention these terms is due to the first ques-
tion many people ask. "What do 1 type in?" Most assembly
listings you find in the magazines are either source code, or a
combination a of source code and M L listings. In all cases,
just remember that the source code starts with the label field.
In inputting text into the editor, always start with the label.

(Dennis Lewandowski, one of the early authors active
with the Color Computer, specialties in machine lan-
guage programming. He and his wife. Rose, founded
DSL Computer Products.)

The following problems, and solutions, are based on the
EDTASM+ cartridge sold by Radio Shack. These seem to
be the most often encountered, and frustrating, problems
for beginners and old hands alike. The most misunderstood
command in assembly language is ORG, which is short for
ORIGINATE. This should be the first command in the text.
It tells the editor/ assembler where the program is to begin in
the computer's memory. If you assemble the program using
ZBUG with the AO (Absolute Origin), and the program
conflicts with any of the memory ZBUG is using you will get
"BAD MEMORY" errors. There are two ways around this,
first don't use the AO option. Second, assemble the program
to tape, and reload it without the EDTASM+ cartridge.
Always save your source code prior to powering down your
computer!

The error "bad label" can be generated many different
ways. The most popular is entering text in which the author
uses a label like "A@." Although the @, or ampersand
symbol, is not a reserved character in EDTASM+, it just
doesn't like it. So don't use it. Instead, substitute another A.
(Example: A@ use AA if you encounter another A@ later in
the listing, which is legal i'n MICRO-WORKS SDS80C, use
another letter like AB.) The other common mistake, which
will drive you crazy, is pressing the space bar prior to press-
ing the right arrow. For some reason EDTASM+ some-
times ignores the space; other times it will use it as part of the
label. For this one it's easiest to just retype the line.

The "multiply defined symbol" error can be generated
with the same ease as bad label. Once you have figured out
that EDTASM+ doesn't like the ampersand symbol you
substitute another letter and get this error. Use the symbol
table generated by the assembler to keep track of the sym-
bols used. You can use the options of EDTASM+ togener-
atejust a symbol table. (Example: A/ NL/ LP would send an
error count and symbol table to the printer.) Also, the first
five characters being the same can generate this error, some-
times! (Is this a bug?)

If you have ever attempted to use the global editing fea-
tures of EDTASM+ and were rewarded with a series of
SEARCH FAILS for your efforts, don't lose faith. Using
the commands you must remember that a space is a valid
character. (Example: F LOOP I would look for the word
LOOP1 preceded by a space, using FLOOPI to find the
word.) Also, when using the renumbering option N. always
move the text pointer to the beginning of text. Otherwise,
renumbering will start at the current line of text. (Now how

did two line number 1 00s get in there?) Use the P# command
first!

Okay, you've completed the program, you have saved the
source code, the object code, and have a hard copy listing.
Still, when you CLOA DM and EXEC you gel pretty graph-
ic patterns, and you typed in a utility program! Hmmm.
something is wrong! The most frequent cause is the EXEC-
ute location. The last line of the program should always be
something like END START . Of course, some authors
use words like ENTRY, BEGIN, MAIN, etc. These words
all refer to where the program should begin running. If the
author omits which label he is using for START, assume the
first label of the program should be the starting address. The
last line of text should always be something like END

START. Otherwise, the assumed execution address is
zero!

Finally, the error message that strikes fear into every
assembly language programmer. "Bad opcode"— it's in the
magazine, but look high and low, you can't find it anywhere
else. You can't even figure out what it's supposed to do! As
usual, there is a way around it. Hopefully there is a ML
listing. Use the FCB to manually insert the byte codes.
(Example: IF 89 4D TAB (ML listing and opcode

as in article.) Substitute the following three lines: FCB
$IF FCB $89 FCB $4D( Remember only one number
per FCB line).)

That's enough for this month. 1 would like to remind you
that if you are having troubles with a program, starting this
month, Dan Downard has a question and answer column.
Please remember that incomplete questions are impossible
to answer, so send questions with documentation and
examples.

TAKING BASIC TRAINING

When A Graphic
Idea Strikes . . .

By Joseph Kolar
Rainbow Contributing Editor

Suddenly, you have an idea! You wonder if it is possible
to make an alphabet out of the graphic characters
available to your CoCo[CHRS(128) to CHRS(255)].
You can't recall seeing it done, and more importantly,
wonder if you could do it. There is only one sure way to find
out. Try it!

Before you dash off to the keyboard, mulling the idea over
in your mind, visualize the problems you might encounter.
Determine your abilities and reference library sources to see
if they are well enough advanced to cope with the problems
you anticipate. If you feel you are not ready to attack the
problem at this point in time, it does not follow that in a few
month's time you will not have acquired the necessary
know-how to tackle the problem.

Make a note of the idea. Describe it as best and fully as
you envision it. File it away for a future project. Ideas are so
fragile and fleeting that it is imperative that they be written
down or they may be lost forever.

Back to the drawing board! First, figure out the smallest
boundary required to enclose all of the letters. Anticipate
which letters might give you a problem. Get a piece of paper
and rule a bunch of lines to make a grid. If you figured out
that you needed a 6 x 6 grid to house the letters, make
boundary lines around 6x6 units. Note that you are really
using a 3 x 3 matrix in the PRINT® Screen Locations. Each
of the graphic characters are divided into four units (two
wide and two down). CHRS(128) has four units which are all
black.

Start by sketching in letters "A," "B," etc. If it looks
feasible, sketch in the difficult ones like "K,""Q,""Y." Are
the likenesses readily identifiable?

Use pencil to block them in. Erase and adjust is the name
ofthegame. Afteryou determine that most of thecharacters
are adequate, you may try a little "hands-on."

Create a training aid at this point. (See Figure 1 .) Fold a
sheet of typing paper in half. Make two rows of eight
squares. Divide each into four equal segments. Label them
left to right as follows: 128; 143; 129; 130; 136; 132; 134; 137.

(Joseph Kolar is a free-lance writer and programmer
dedicated to proselytizing for computers in general,
and the CoCo specifically. J

Drop to the second row. Again, from left to right, number
them: 135; 139; 142; 141; 133; 131; 138; 140. Color in the
appropriate segments of CHR$(I28) to CHR$(142).

Notice the pattern. Top row: All on; all off. Next four:
three of the four units are colored black, in a clockwise
direction. Last two: diagonal down; diagonal up. Bottom
row: four left blocks have one segment colored black and the
last four have two adjacent segments colored black.

At the left edge of your training aid, in a column entitled
"PRINT@," list vertically 0; 32; 64; 96; 128; 160; 192; 224.
These are the rows above the horizontal centerline of the
screen. A few spaces to the right of 0, continue in a second
column: 256; 288; 320; 253; 384: 416; 448; 480.

On the right side, print undera column labeled. "COLOR":
143+16 yellow. Then, under the "+," continue with +32
blue; +48 red; +64 buff; +80 cyan; +96 magenta and +1 12
orange. If the colors on your monitor orTV screen are other
than what you have listed, you can make appropriate notes.

Place the completed chart between the air vents of the
CoCo. You will be able to refer in a logical sequence to the
chart when looking for a shape. Under the shape will be
CHR$ number. You will find this chart useful so don't
throw it away.

How would you create a letter using the graphics,
CHR$(128) through CHR$(I43)1 Sketch in the shape of the
letter. Consult your training aid to see which combinations
you have to work with. Break up the 6x6 grid, so that you
have four unit squares like the CHRS graphic element.

Look up and see which CHRS character is exactly the
same as the contents of your 2x2 blocks.

A square-topped "a" will fit a 3 x 3 box nicely. The first
row could be labeled [AS]; the second [B$] and the bottom
row. [C$].

Putting them into program lines you would have:

10 A$=CHR$(I29)+CHRS(I31)+CHR$(I30)
20 BS=CHR$(I32)+CHRS(I40)+CHRS(I36)
30 C$=CHR$(133)+CHRS(143)+CHRS(138)

AAS designated the completed letter by combining the
elements of the three rows.

500 A A$=A$+B$+C$ 'square top

This was done using concatenation, a long word that
translates to [+] in BASIC. This is the sign for "adding to,"
but, unlike the plus sign, +7, it doesn't add something to
change the total and thus becoming an invisible part of the
result. In 2+1=3, the resultant 3 has the hidden parts. 2 and
I.

Concatenation is always visible. Concatenating 2+ 1 results
in 2 1 . Both 2 and 1 are visible in the resultant 2 1 .

If you created an "A" with a pointed top, an odd number
of columns would be required — five in this case. The letters
"I"and"T" require an odd number of columns. Remember,
you will still use the 6x6 grid or matrix because an even
number of columns must be used to fill in the entire CHRS
graphic character.

Make a sketch of the letter. "X," using six columns and
then one that uses five columns. Which one do you like
better?

In order to display the "A," we have a problem. Even
though [AAS=AS+B$+CS] is a completed "A" in three
component rows, it can't be printed using a simple program
line. Type in and RUN lines 10-30: 500: 800. The top row is
printed with the second row to the right of it. followed by the
third row to the right of the second row. Interesting — but
garbage!

The three rows that constitute the A must be printed one
below the other.

Look in your manual at the "PRINT@ Screen Loca-
tions." Pick the row that starts just below the horizontal
centerline — 256. Notice you have the list on your handy
training aid. Add one to 256 to leave a blank area at the left
margin. Key in the following three lines:

800 PRlNT@256+l,A$'top row
810 PRINT@288-H,B$'middlerow
820 PRINT@320+l,C$'bottom row

286

the RAINBOW February 1984

RUN. Note you could have just as easily used PRINT
@257; PR/NT@289; PRINT@321. It is easier to refer to
the starting number of each PRINT@ row and [+] whatever
number you wish to move your A horizontally on the screen
to a desired location. Try other numbers instead of [+1] but
be sure to add the same offset to all three rows.

To make a five column, pointed A to see how it compares
with a six column, square top A, you get:

40 D$=CHR$(I43)+CHR$(134)+CHR$(143)
50 ES=CHR$(132)+CHR$(I40)+CHR$(133)
60 F$=CHRS(133)+CHR$(143)+CHR$(133)
500 A1S=D$+E$+F$

Change the variable in lines 800-820 to D$; E$ F$ respec-
tively. RUN. Which one do you like better?

It might be a good idea to compare them side by side. At
the end of lines 800-820 add [;A$], [;B$], [;C$] respectively.
RUN. Hey, something's wrong! The two letters run into
each other. Have no fear!

There are a few ways to remedy the problem. You could
go back and add [+CHRS(143j\. an empty graphic block, to
the ends of lines 10-60. A better way would be to create a
variable, [SP$], a spacer. Insert:

5 SP$=CHR$(I43)

Instead of adding [+CHR$(I43j]. 10 bytes of memory to
each line, 23 add [+S PS] and use four bytes per line. Another
way would be to add, either [CHR$(143j] or [+SPS] after
each variable in lines 800-820. It would be: 800 PRINT
@256+I. D$CHRS(I43); AS+SPS' example using both
methods in a single line.

After you experiment, choose your solution. Adjust the
program lines to reflect it and RUN the program. You may
find both letters okav but wonder if there are other possible
A's.

Try to design other shapes. Always try to alter or improve
all problems. Keep trying variants until you run out of ideas.

Get out your scrap paper and sketch out some other A's. If
you find some new design or format for an A, see which
program lines are altered. Assign it a new variable name and
add additional lines to your program. In lines 800-820, add
the components at the end of the line, remembering to add a
semicolon between variables. This indicates that the last
variable is to follow to the right of the previous variable.
RUN and see how it compares with the others.

A good idea is to change lines 500-510, by adding a REM
so you can recall which set of variables constitute a specific
form of A.

500 'A$+B$+C$ square top
510 'D$+E$+F$ pointed top

To keep you honest, no further hints will be given. In the
next article, we will consider the letter A further and develop
more information about expanding this core program, that
you are in the process of creating. Make as many A's using
this format to sec how many you can come up with.

An added project for you is to create an entire alphabet.
Fool around with it. You made two A's and are creating
more variants. There is no reason for you not to create all the
letters of the alphabet and have fun getting familiar with the
graphic blocks.

As an announcement in your magazine,
we would like to briefly point out some of
the advantages of joining us and outlining a
few services that can be enjoyed by anybody
anywhere, if he/she wills.

A member of MTUG will enjoy our down
time service which simply entails the use of
another member's equipment as long as
his/ hers is indisposed. Also our members
enjoy a purchasing service; anything the
member buys through the club is charged at
a discount. Members (anywhere) have use of
our exclusive Bulletin Board System which
includes a "classified ad" department and
electronic mail. A newsletter is also pub-
lished bimonthly and is available to anybody
who wants it. Members get a free subscrip-
tion to it. Advertising is also accepted from
anybody at a nominal rate. This makes
MTUG unique in Montreal.

What Is Your
Compatibility Rating?

By Simon Clift

This is a program I have wanted to write for a long
time, but a couple of weeks ago an idea struck me
that really made sense. If you wanted to write a
program that tested your compalability with another per-
son, your questions would have to be on those things that
couples found most annoying, 1 mean, forget nuclear arms,
how many kids to have, or financial dealings, anyone can
agree on those earthshakers. You have to get down to the
nitty-gritty things that bother people who live around each
other.

J developed this program following surveys of many cou-
ples to see what bothered them most. As a result it reflects
some of the most aggravating little things.
The format is as follows:

Analysis

Try this program on your friends at a party perhaps. Also,
if you like, you could add a routine to save the results on disk
or tape for a dating service program, or just for fun to see if
you and that special person were "meant to be." Anyhow. I
hope you enjoy it. Rainbow Check

Inputting Your
Role Playing
Characters

By Bob Albrecht

and
George Firedrake

Last time we showed you two simple programs called
KE YBOA RD-MEMOR Y- TA PE and TA PE-MEMOR Y-
SCREEN. Next, let's write a program to put information
about role playing characters on a cassette tape. When you
run our program, the CoCo asks for the name of your
character and the values of the seven basic characteristics.
Here is what happened when weentered Aloysious's charac-
teristics.

CHARACTERS TO TAPE

NAME OF CHARACTER? ALOYSIOUS

SIR? 10
CON? 1 1
SIZ? 10
[NT? 12
POW? 10
DEX? 12
CHA? 9

OK TO PUT ON TAPE (Y OR N)?

Alter the CoCo finished putting the information in the
tape buffer the screen looked like this:

CHARACTERS TO TAPE
NAME? ALOYSIOUS

SIR? 10

CON".' I I

SIZ? 10

INT? 12

POW'.' 1(1

DEX? 12

CHA? 9

OK TO PUT ON TAPE (Y OR N)?

ABOVE RECORD IS IN TAPE BUFFER

TO ENTER A RECORD. PRESS SPACE

TO CLOSE FILE. PRESS T

When the CoCo asks OK TO PUT ON TAPE (Y OR N)7.
you might type N for no. In this event, you will sec the
following.

(Bob Albrecht and George Firedrake are two of the
most prolific authors in the microcomputer world
today. Specialists in writing for beginners, they are
authors of numerous books, including TRS-80 Color
BASIC.)

Here is the first part of the program.
lOOO REM**CHARACTER RECORDS
1010 OPEN "O", -1, "CHARACTERS"
1020 CLS
1030 PRINT "CHARACTERS TO TAPE"

Line 1 1 tells the CoCo to open a cassette file for output.
The file is called CM A RA CTERS.

1010 OPEN_"_0"> -1, "CHARACTERS"

Open lor output
to cassette

a file named

Line 1010 is written for Extended Color BASIC. If you arc
using Color BASIC, write line 10I0 as follows:

I0I0 OPEN "0", #-l, "CHARACTERS"

Put a # sign here.

Next, let's get the information to put on tape, the name of
the character and the seven basic characteristics.

1100 REM**GET CHARACTER INFO

1110 PRINT: INPUT "NAME"; NAYM*

1120 PRINT

1130 INPUT "STR"; STR

1140 INPUT "CON"; CON

1150 INPUT "SIZ"; SIZ

1160 INPUT "INT"; INQ

1170 INPUT "POW"; POW

1180 INPUT "DEX"; DEX

1190 INPUT "CHA"; CHA

After someone has entered the information about a char-
acter, the CoCo wants to know if it is okay to put this
information into the cassette file.

1200 REM**OK TO PUT ON TAPE?

1210 PRINT

1220 PRINT "OK TO PUT ON TAPE <Y

OR N)?"

1230 K*=INKEY$: IF K$=""THEN 1230

1240 IF K*="Y" THEN 1310

1250 IF K*="N" THEN 1020 ELSE 12
30

If someone typed Y for yes, the CoCo writes the charac-
ter's name and seven basic characteristics into the tape
buffer.

1300 REM**PUr RECORD ON TAPE
1310 PRINT #-1, NAYM$,STR,CON,SI

Z, INQ, POW, DEX, CHA

1320 PRINT @416, "RECORD IS IN T

Now you get to choose whether to enter another character
record or to close the file.

1400 REM**WHAT TO DO NEXT

1450 IF K*="C" THEN 1510 ELSE 14

1500 REM**CLOSE THE FILE

1510 CLOSE -1

1520 CLS

1530 PRINT "THE FILE

1540 END

Your Turn.

Write a program, beginning at line 2000. to read and
display character records from the character file on a
cassette tape.

Also write a program, beginning at line 3000. to search a
cassette tape for a record by name of character. Of course,
you will have to rewind the cassette each time before you do
this.

Aloysious Anonymous is an average character, destined
to be other than an adventurer. Here he is at age 16, a young
person living in a village near Triford in Wundervale.

MONEY

In future episodes of "GameMaster's Apprentice," we will
expand our simple programs to include more information
about a character, as suggested by the character sheet.

• The numbers under SKILLS are success percentages
for performing the skill under ccrtan conditions. Aloys-
ious has a 55 percent chance of CLIMBing and a 45
percent chance of connecting when he THROWs.

• Do you have a printer? II so. think about how to write a
program to print a blank character sheet or a program to
print a character sheet containing information about a
character.

• Yes, we want to put everything on a character sheet in a
cassette file and read it back when we want to store it in
memory or display it on the screen. Too much for a
screenful! So. think about how 10 organize and present a
complete character record in memory and on the TV
screen.

The items listed on the character sheet are only a begin-
ning. Many other skills arc possible. Aloysious, at age 16,
has not acquired magical spells. We have included nothing
under EQUIPMENT or MONEY. The description of a
character is open-ended. Please keep that in mind when you
write programs.

The Name File

We suggest a program for you to write. It goes like this.
Type RUN and you see:

r

RANDOM NAMES TO CASSETTE
NAME STRUCTURE?

The CoCo is waiting for you to enter a consonant-vowel
structure for the names you want it to randomly contrive.
Okay, let's try CVCVC for Consonant-Vowel-Consonant-
Vowcl-Consonant.

RANDOM NAMES TO CASSETTE

NAME STRUCTURE?

CVCVC

CONAN

PUT ON CASSETTE (Y OR N)? ■

If you press the Y key, the CoCo writes the name on the
cassette. If you press the N Key, it doesn't write the name on
the cassette. In either event, next you see:

RANDOM NAMES TO CASSETTE

NAME STRUCTURE? CVCVC

CONAN

PUT ON CASSETTE (Y OR N)? Y

TO QUIT, PRESS -Q'

FOR ANOTHER NAME. PRESS SPACE

FOR NEW STRUCTURE. PRESS 'S'

If you press the Q key. the CoCo closes the file and stops.
You decide what it says on the screen to announce what it
has done. If you press the [SPACE] bar. the CoCo generates
another name using the same name structure. If you press
the S key, the CoCo asks you for a new name structure.

Hmmmm. . .you might find the following subroutine useful.

30000 REM**GET I KEY SUBROUTINE

30010 KKS=1NKEY$

30020 IF KKS="" THEN 30010

30030 RETURN

When you want the CoCo to wait for a keypress, simply
write GOSUB30010, then use KKS to find out what key was
pressed.

FAST AS 1' ROLE PLA YISG GAMES

Millions hi young people, anil many not-sa-young, are playing fantasy rule playing
games. A role playing.game is a game in which one or more players create and control
characters (adventurers) who live their imaginary lives in a specially made game world.
The game world is treated, managed, and operated by a Game Master (GM). also
called a referee, adventure master, or dungeon master (DM).

Most people ii ho play role playing games use a formal rule system. Some of the best
know n are shown below.

Champions. From Hero Games. 92 A 21 si Avenue. San Mateo, CA 94402.

Greetings!

I sat out on the front porch the other night, looking at the
stars. Then 1 heard an ominous click — Bertha (may her
name be whispered with reverence among the immor-
tals) had locked me out. It was freezing cold out there, bin 1
got to look at all the stars in the sky for a long time. The stars
out here in the country are bigger and brighter than city
stars, you know. Anyhow, I started thinking about stars,
and decided that as soon as I got inside the house I would try
a few on my Color Computer. I spent the rest of the night
communing with Ben, in confined but cozy quarters. The
next morning, 1 managed to get inside the house, and went
downstairs to my computer. 1 thought about several ways 1
might try to do stars, and equal-sided, equal-angled triangles.

(W. Bert Woofensburger [" Uncle Ben"] manages a
hog and corn farm near Ypsilanti, Mich. He has
recently acquired a Color Computer and is learning
LOGO. Woofensburger 's editor and assistant. Dale
Peterson, writes for a living. His recent books include
"Genesis II: Creation and Recreation With Compu-
ters" and "Intelligent Schoolhouse: Readings On
Computers and Learning. "He is currently working on

the RAINBOW February 1984

Just to play around and remind myself about the angles
involved. I made an equal-sided, equal-angled triangle:

TO TRIANGLE

REPEAT 3 (FD 60 RT 120)
END

And I made an equilateral pentagon:

TO PENTAGON

REPEAT5(FD60RT72)
END

Then I played around with triangles and pentagons that
had variable sides:

TOTRIANGLE2:N

REPEAT 3 (FD:N RT 120)
END

TO PENTAGON2 :N

REPEAT 5 (FD:N RT 72)
END

Then. I thought about the angles of turtle-turning that
would be involved when triangles are stacked around a
pentagon, and came up with this star:

TO STAR :N
RT30
REPEAT 5

(FD:N RT I20FD:N LT 48)
END

And I tried various values for :N. including 10. 20. 35 and 50.
My star was always starting at home position, which was
all right. 1 suppose. But I wanted to try other positions on
the screen. Now, in the past when I've wanted to start a
drawing at a position other than the home position. I've
always just snuck the turtle over bv telling it to PENUP
(PU). then move over, then PEN DOWN (PD). But. I've
recently discovered a new way. Apparently, positions on the
Color Computer's screen can be described by numbers.
There are X numbers, which describe locations widthwise
across the screen. Then there are Y numbers, which describe
locations up-and-down-wise on the screen. With Color
LOGO, you can place the turtle anywhere on the screen by
specifying the X and Y locations you want, using the follow-
ing commands: SETX and SETY. It seems that you can
choose your X locations with numbers from to 255. and
your Y locations with numbers from to II. The turtle's
"home" is in the middle of all that, at a position where X
equals 128 and Y equals 96.

r

^ 255 ^

191 X

I

Y

/\

HOME
X=128
Y=96

Anyhow. I decided to try a star that was just a little higher
than the home position (thus using a SETY that was greater
than 96). Did I mention that the abbreviations for SETX
and SETY are SX and SY?

TO STAR I :N
SY 1 20
REPEAT 5

(FD:N RT 1 20 FD :N LT 48)
END

Then I said to myself. "What the heck — if the number of
a side length can be a variable, why can't my X and Y
values?" So I tried that.

TOSTAR2:N :X :Y
PC I

SETX :X SETY :Y
REPEAT 5

(FD:N RT 1 20 FD :N LT 48)
END

Next. I tried my usual fancy-dancy variations.

TOSTARSTAR :N
SY 120
REPEATS
(PC I FD:N RT I20
PC 2 FD:N LT48)
END

TO STARSTAR2 :N

REPEAT 50 (STARSTAR :N RT I )
END

I didn't really like STARSTAR2 :N very much. I had been
hoping for a kind of star-circling effect, something neat and
symmetrical. I thought about what was happening and
realized the trouble was that my star was always beginning
at a "valley" on the star's edge, and that beginning position
was making everything mush up. So l decided to start my
star from a lip and then try to spin it around. Thus. I did this:

TO STAR3 :N
FD:N
REPEAT 4

(LT48 FD:N RT I20 FD :N)
LT48 FD:N RT 120
END

TO STARCIRCLE :N

REPEAT 20

(PC I STAR3 :N RT I8)

END

I picked the number 20 at random, thinking that would
look nice. The RT 1 8 arose because I wanted the repealing
star to fill a whole circle (18 times 20 brings us all the way
around to 360). Thinking about that I realized I might make
effective use of a second variable for the number of times the
pattern repeated.

TOSTARCIRCLE2:N:T
REPEAT :T

(PC I STAR3 :N RT360/:T)
END

I decided to get fancier:

TOSTARCIRCLE3 :N :T
REPEAT :T/2
(PC l STAR3:N RT 360/ :T
PC 2 STAR3 :N RT 360/ :T)
END

And fancier:

TO STARCIRCLE4 :N :T

February 1984

the RAINBOW

MAKE:M :N/2
STARCIRCLE3 :N :T
REPEAT3(PC0STAR3:M RT 120)
END

Next. 1 thought it might be nice to build a star that would
fill itself in. One possible way to do it might be to run the star
outline procedure (TO STAR3 :N), and keep reducing the
value of :N. How do we reduce the value of :N? We could run
STAR3 several times, and each time specify the value of :N
by typing it out. But that means too much typing for Uncle
Bert. Fortunately, there is an easier way, and it has to do
with the MAKE statement. The MAKE statement allows us
to include variables internally within a procedure, and
change them automatically, as part of the procedure. Not
clear? Let's try it:

TO STAR FILL
MAKE :N 25
REPEAT 25 (STAR3 :N
RT 30 FD I LT 30
MAKE.N :N-I
END

Neat, huh? I like the way the size of :N diminishes auto-
matically in the procedure. For various reasons beyond our
control, that did not completely fill the star. So. we'll keep
that procedure and then sneak a long the edge of the star and
do it again from one of the other tips. Like so:

TO STARF1LL2
STARFILL
HOME
REPEAT 3

(FD25 LT48 FD 25 RT 120)
STARFILL
END

Not perfect, but good enough for me. No. I'll give the
whole thing a better color, and tilt it:

TOSTARFILL3
RT 5 PC I
STARFILL
HOME RT5 PC 1
REPEAT 3

(FD25 LT48 FD 25 RT 120)
STARFILL
END

Notice that I have to specify pcncolor after HOME. The
HOME seems to cancel previous conditions, including pen-
color. No, to make my filled star really mobile. I ought to
introduce variables for position. Like so:

TOSTARFILL4:X:Y
SX :XSY :Y
RT 5 PC 2
STARFILL
SH0SX :XSY :Y
RT 5

REPEAT 3

(FD25 LT48 FD 25 RT 120)
STARFILL
END

1 putintheSH0(SETHEADING0)justtomakesuremy
turtle was pointing straight up before I went into the rest of
the procedure. Try that one. with various values for:X and
:Y. All right - enough pussyfooting on little cat feel, as the
poet says! So. try this:

TO FIELD
HTPC 1
MAKE:Y

191

That gives a red star in a blue field. To avoid serious
misunderstandings at the international level, go back to the
STARFILL4 :X :Y procedure, and change the pencolor to
3. You may also want to experiment with the PCs in FIELD
and in STRIPE and STR1PE2. and with COLORSET, to
get the proper and patriotic blue and red. Now:

PRINT #-2, (continued from p. 14)

It seemed like every time 1 was turning around last month
someone in the office was handing me an airplane ticket for
someplace. The highlight of the rhonth was a trip to Las
Vegas for the COMDEX show. It was somewhat disap-
pointing in that there were so many "new" computers on
display — with, to my mind, no chance that they will all
survive in the marketplace in the coming year.

But the biggest news of the show — or the most-talked-
about product - was the new IBM PCjr, computer.
Frankly, it was a disappointment forme. My feeling is that it
is priced too high, does not have the gloss of the IBM PC,
and may have rushed ahead to get into an under-SI.OOO
market. It barely makes it into that category and I. for one,
think it will be a real test of whether the American public will
buy a computer for the capabilities or the "name."

I also took a few days to attend the World of Commodore
show in Toronto, and was pleased to see several of our
Canadian friends who were, as I was. checking out another
market.

What impressed me most about the show was the attempt
by Commodore to absolutely dominate their computer's
market. Radio Shack has always had a bad rap — usually
from one source which will go herein unnamed - for being
"closed" to the third party market. If anyone wants to pin
that rap on Radio Shack today, they should look at
Commodore.

Come to a RAINBOWfest and you will see a variety of
printers, modems, disk drives and the like. Certainly. Radio
Shack equipment seems to predominate — but part of that
reason, 1 firmly believe, is because firms which manufacture
disk drives and printers do not actively market to the CoCo
(see, for example, the number of such manufacturers who
directly advertise on these pages).

Yet. in Toronto, what I saw were Commodore disk drives.
Commodore printers. Commodore monitors. Heck, there
were even two Commodore company magazines. And the
magazines do not accept advertisements from third parties.
What I am saying is that Commodore really tries to
dominate its market. And, I believe, one of the reasons
CoCo has been so successful is because of the participation
of third party vendors in the market. My opinion is that this
is a forward-looking approach on Tandy's part and that they
don't deserve the bum rap that some people try to pin on
them.

By the way, I think, too, that the dominance of Commo-
dore in its own market very badly hurts what some call
"kitchen table software" firms. If you have to compete
directly with the people who make the computer, you have
to have a certain "bigness" about you. I know lots of people
who started up in the CoCo market on a shoestring {the
Rainbow included) and I still believe the Color Computer
offers an opportunity for good old incentive, no matter how
small you may be.

It would be unfair for me to mention the Commodore
show without mentioning the warm-hearted people of that
fine city. In three days north of the border, I did not encoun-
ter a single person who was not a first-class representative of
a wonderful country. From the guard at customs to the taxi
drivers (who I think \ convinced to buy a CoCo). everyone I
met or spoke to was warm, friendly, helpful and, as we say
here in the south, "good folks."

You have no doubt read things I have to say about Radio
Shack from time to time that have been very positive. Well. 1
suppose you should know that those are not just words.

From the beginning, we have used Radio Shack equip-
ment in the business end of the Rainbow as well as the
publication end. We do that because we have a very good
feeling for the reliability of the equipment and. too, because
we don't feel we have to be programmers to make it work.
We use Color Computers for a variety of things besides just
publication of the Rainbow and its sister computer maga-
zine, PCM — The Portable Computing Magazine.

As an example, we are able to use Color Computers to
typeset copy for the magazines through our typesetting
equipment and, in the case of another publication, SCORE-
CA RD. a sports weekly, we use Portable Computers to do
statistics and write game stories.

We have a Radio Shack telephone system which works
very well and we have historically used Model lis, 12s and
16s for our subscription service, general accounting and the
like.

Just this past month we took another step, and began
conversion to a multi-user environment for subscription
service on the new Xenix software from Radio Shack. One
of the prime reasons for that decision was the case of con-
verting our present subscription data files from single-user
Model 16 to Xenix. It means faster answers to your sub-
scription queries, for one thing. And it also means that now
we can have more than one person entering new subscrip-
tions (or updating renewals) at a time. We've been growing
very rapidly, and the need for this single feature has become
a must. By the way, if your subscription label last month was
a little bit different (perhaps no expiration date) blame it on
the dummy (me) who forgot to put it on. It is fixed now.

I guess what 1 am saying is that you often read here about
how good I think this or that at Radio Shack is. We don't
just say it at the Rainbow, we believe it and practice that
same philosophy.

A Teeny Tinydump

By Dave Anthony

Here is a 2-line program which will dump PMODE
0, 2 and 4 graphics to a DMP-100 printer. I
wrote this program when I was unable to find one
elsewhere that would print one dot per screen point. The
program gives a small picture, which helps to overcome
CoCo's low pixel resolution, hence, the name Tinydump.

Being in BASIC, it can take a good deal of time to print one
screen. However, it is simple and relatively easy for an
intermediate CoCo programmer to understand.

Since a hi-speed poke is used, CoCo should be set to
output at 600 Baud, which will effectively be 1 200 Baud. The
printer should be at 1200 Baud.

Tinydump is a poor person's screen dump, requiring
Extended BASIC and the least expensive printer Radio
Shack makes.

Here is an example of Tinydump:

David C. Owen tells us that we made an error in illustrat-
ing his article, "Build An RS-232 Device Select Switch For
Under $20" (December 1983). On page 204, the template in
the upper right corner shows locations for holes to be
drilled. These are not properly centered. All markings
should be made along a horizontal center line, which would
raise them a bit from where they are shown in the
illustration.

In Richard S. Ellis' article, "Install Your Own Disk Drive
'On/ Off Indicator" (November 1983), instruction number
three was inadvertently omitted. It should read:

3) Refer again to the attached picture and find the OV
strip [ground]. Solder a black wire (prestripped on both
ends) at the point indicated. You will find another hole in
the board here.

A clarification rather than a correction needs to be made
concerning Joseph Kolar's article, "Flaunt Your CoCo With
Season's Greetings Cards" (December 1983). While this
novel program performs as indicated, you need to have a
printer with a "bit-image" graphics capability and a screen
print program that matches your printer in order to get
printed copies of the cards. Good luck with St. Valentine's
Day!

There Are Many Features

To Consider When Purchasing

Disk Drives

m

ould you please have someone
run a comparative review on disk
drives available to the CoCo?

Sieve Hewitt
Leeton, MO

The choice of disk drives is a toss-up for
the CoCo. Steve. Without getting into spe-
cific brand names we can give you some
things to look for:

Two characteristics, which are very impor-
tant for drive selection, are the number of
tracks and the track-to-lrack access lime.
The standard Radio Shack drive is capable
of 37 tracks (even though only 35 are nor-
mally used) and has a track-to-track access
time of 30 milli-seconds. Sounds pretty fast,
doesn't it? Disk Extended basic assumes
you are using this type of drive and the soft-
ware is based on these values. As the soft-
ware is in ROM, it cannot be changed.

Other disk drives on the market are capa-
ble of 40. and even 80 tracks, and have access
times of as low as 6 milli-seconds. These
drives will work with Disk BASIC. You can
onlv use 35 tracks and 30 milli-second access

(Dan Downard is an electrical engi-
neer and has been involved in elec-
tronics for 24 years through ham
radio [K4KWT|. His interest in com-
puters began about five years ago and
he has built several 68XX systems.)

though due to Disk BASIC.

Then there are DOSes (Disk Operating
Systems) for the CoCo. The three most
common are FLEX, STAR-DOS and OS-9.
These DOSes allow a variable number of
tracks and different track-to-track access
times. When using a true DOS on the CoCo
disk, access frequency is far greater. As each
program is loaded only when necessary, it
becomes important to have fast disk access
times. Obviously, the number of tracks is
proportional to the storage capacity of the
disk. The more the merrier. From a storage
capacity standpoint you are far better off
with 40 tracks.

There are other considerations loo. such
as price. Beware of the bare drives advertised
in some trade publications. That is exactly
what you get: No power supply, no case, or
no controller. When you buy a Radio Shack
Drive 0, all you have to do is plug it in and
you're in business. Other drives will requirea
controller and cable.

Taking all of the above into considera-
tion, I would recommend that the average
user buy a Radio Shack drive. If you are
confident you can handle the interfacing,
there are other drives on the market that are
faster and have more storage capacity. Keep
in mind that to utilize these features you
have to be running a DOS. We understand
that one company now makes a controller
that is compatible with Disk basic and
allows you to reconfigure your disk drive

without a DOS. but this controller has not
been reviewed. Good luck.

CoCo Amnesia

• Using the instructions in the June 1983 edi-
tion of Rainbow, J extended my 16 K "285"
ECB. I put 64K chips in it. Now, when I
"'MEM" I get 24871. A POKE 25,6:NEW
will raise the memory to 3 1015, but that 's it.
Is there a modification I must make to my
285 hoard to get the memory up closer to
64K? Or. what do I have to type in to get it?

Ron Hestand
Radcliff. KY

There is nothing wrong with your compu-
ter, Ron. You already have 64K of RAM.
but you have to know how to use it. There
are two things you must understand, the
difference between RAM and ROM. and the
memory map of your CoCo.

Even if you have 64K chips installed,
when you turn on your computer it is initial-
ized such that the lower 32K. or S0000-
S7FFF. is configured as RAM and the top
32K. or 58000-SFFFF. is configured as
ROM. Since Extended BASicdocsa PCLEA R-
4 and CLEAR20Q on startup, you have
24871 bytes left for basic programs. This is
normal. The POKE 25, 6 statement you refer
to is actually a PCLEA R0 and gives you 6K
of additional memory, if you don't require
memory for graphics.

308

the RAINBOW February 1984

How do I use the upper part of the 64K
RAMs? There are several schemes of using
some of this memory. One particularly pop-
ular way is to move BASIC from ROM to
RAM. and then relocate basic. With this
method, programs of up to 40K a re possible.
If you want to try this see Jorge Mir's article
"Using The Upper RAM of Your 64K" in
October's Rainbow. Using the upper 64 K. of
memory is not automatic and requires some
imagination. Some other common uses for
this "unused" memory are high resolution
scrccils, data storage and printer spooling.

Use Your Chips Wisely

•/ have a TP-10 primer but can 'I gel it to
work properly. It isn 't the printer, it works
fine on another Color Computer. It isn V my
RS232port. Iran the Radio Shark Diagnos-
tic ROM Pack RS232 test audit tested okay.
The only other thing I could think of was
that I upgraded my D board from it 's origi-
nal 4K to it Is present 32 K by piggybacking
the RA M chips.

My mind flashed back to a letter to the
editor in the October issue o/Rainbow. His
problem was with "color script. " You said
that piggybacking RAM chips produces
"memory overlay" that produces havoc with
certain software. Could this "memory over-
lay" be the problem with my printer also? If
so maybe someone knows of a poke that
would solve the problem.

Joe Hadlev
Ft. Ord. CA

Joe, when you piggyback a set of I6K
chips, pin 4 of the top set of chips is con-
nected to pin 35 of the SAM chip. Pin 4 of
the 4II6-I6K Dynamic RAM is the RAS
line, or the row address strobe. Pin 35 of the
SAM chip is MA7, or in the case of piggy-
back RAMs, RAS1.

Whai all of this means is that your addres-
ses are not absolutely decoded and each byte
appears twice in the memory map. Addresses
$0000-57 FFF correspond to addresses $8000-
SFFFF. what we normally call a memory
overlay. Forexafnple. if you would examine
address $0400 with a monitor, the byte value
would correspond to the value at $8400.

Software associated with the printer rou-
tine polls the SAM and consequently the
PI A chips for a printer busy signal at address
$FF22. Bit 0. Since you have both R A M and
the PIA chip at this address, a problem is
created.

Our advice is to upgrade to 64 K using
4 1 64 chips. In addition to solving your prob-
lem, your computer will run cooler and you
can make use of 64K software offering many
new advantages.

A Talking Gorilla?

• lam writing in reference to Tony DiStefa-
no 's article on Page 230 in the November SJ
issue. / have a Gorilla monitor and as you
are aware, it doesn't have an audio output.
The article shows how to hardwire a speaker
and amp inside the computer, but I wanted
to know if there was some device to be con-

nected outside the computer, possibly using

the present jack.

Scott Nelson
Atlanta, GA

Scott, the same circuit you are referring to
in the November Rainbow Could be installed
in your monitor just as well as inside your
computer. The only problem may be locat-
ing a source of 12 Volts DC.

Any audio amplifier will work with the
CoCo. Just pick up the audio input from the
point listed in the article. If you have trouble
finding a source of voltage, try using a
battery.

Same Language, Wrong Dialect

• When I bought my TRS-80 CoCo from a
local Radio Shack Computer Center, the
salesman told me that I could purchase an
adapter so I would he able to use different
cartridges with this Co Co. But, he never has
been able to find this information. Is there,
in fact, such an accessory for my CoCo? Can
I purchase an adapter so my TRS-80 can use
software designed for Atari or ally other
computer system?

Raymond Patrick
Niagara Falls. NY

I think you received some bad informa-
tion, Ray. 1 assume you are referring to
Atari cartridges. Since Atari uses a different
microprocessor, the machine codes arc not
compatible. At the same time. 1 think just
about every game written for the Atari is
available for the CoCo. Just read the ads
carefully.

A Dislocated Disk

• Several of my machine language programs
load at HEX 600. Disk BASIC also occupies
some space at the same address. While I can
gel a disk copy by loading with an offset and
then saving, the programs are apparently
position dependent and cannot be relocated.
The question then is — can that portion of
Disk basic, which loads at HEX 600. be
relocated elsewhere in RAM without crash-
ing my system?

Gary Levcnthal
Latham, NY

Gary, the area above $0600 in Disk basic
is reserved lor disk buffers, the area of
memory that is used lo transfer information
from disk to RAM. As far as we know, there
is no way to relocate this area.

To solve your problem, you might try
appending a short relocator program lo the
end of your game so that after it is loaded
into its offset address from the disk, you
move it back to its original location.

RANDOM BASICS

Design And Development
Of Application Software

By Paul Searby

Since this is the first time an article by me is appearing
in the Rainbow, I will first take a moment to give you
a brief summary of my background. I have been
involved with computers and data processing since 1969,
working primarily on larger IBM systems until 1977. During
that time, I was primarily involved in the design and devel-
opment of both financial and manufacturing applications.
In October of 1975, 1 bought, built and programmed the first
"personal computer" ever made. It was an Altair 8800 that
came in kit form with I K of memory. Then in March 1976,
Southwest Technical Products introduced their Motorola
6800 computer kit, and we immed iately became one of their
first dealers, operating a small store on a part-time basis.
This particular computer is of some interest, because it is
basically the great grandfather to the CoCo.

We were having some success with our small enterprise
and, in October 1977, 1 quit my full time job as a Project
Manager for a large corporation to devote full-time efforts
to our company, Computerwarc"". It was at this time that we
began development of the many system and application
software products that are still being marketed today. In
fact, today, not only do we provide a large number of
products for the CoCo. but still support larger 6809 based
systems. Many larger companies, such as Kaypro Corp., use
the systems and applications products that we developed.

Although I have not personally programmed every one of
the many application packages that we offer, I have always
been involved in the design and development. What I have
had is an opportunity to see the evolution of a particular
series of programs over a period of more than six years,
seeing where they did well and where problems occurred.
That brings us to the purpose of these articles.

What I will try to do is to cover in fair detail the steps
which should betaken in the process of designing and devel-
oping a major application. Although the articles should be

of interest to most people, they will be oriented toward the
designer and programmer (often one and the same). It will
be assumed that this person is not necessarily going to be the
user and thus the additional responsibility of ease of use will
be ours.

As I discuss our design and programming objectives, you
will get the feeling that it is oriented toward a person doing
this for commercial purpose, not you doing it for yourself.
While that may be the case. I would like to point out that it is
from that perspective that better design and programming
habits are developed. Today you think that you are writing it
foryourown personal needs. However, if it is well done and
appears to serve a common need, wouldn't it be nice to
financially reap a reward for your efforts?

The design and programming will be based on the fea-
tures, capabilities and limitations of Computerwarc® Ran-
dom BASIC, which is available for the CoCo on both the
FLEX and OS-9 operating systems. As we go, specific
examples from existingapplication programs ill be included.
However, the reader can use the ideas shown here with
almost any other language. As will be mentioned several
times in the articles, application software is more often
requiringmodificationthanothertypesofsoftware.Thus.it
is a good idea to use a higher level language, which generally
makes minor modifications easier to perform.

Although one of the ground rules for these articles was
that I will not provide extensive "hand holding," ie, over-
simplify, it will be helpful from the onset to provide an
overview of the types of software and the characteristics of
each in relation to our subject of application software design
and development. Basically there are two general categories
for software: system software and application software. Sys-
tem software is typically considered to be not only the
operating system that you are using, but also, the languages
(ie, BASIC. PASCAL. FORTRAN, c. etc.) and most utilities.

THIS N THAT

The BIG NEWS this month is that OS-9 has
finally arrived for the Color Computer.
The ASTOUNDING part of the Radio Shack
OS-9 Package, besides the price, is the
DOCUMENTATION. You 'Old Time Radio Shack
Followers' will not believe what you see.
Jon Shirley has been telling us that the
main reason for the "lack" of
documentation with a lot of their
products was the restrictions placed on
releasing that information by Microsoft; I

OS-9 on the COLOR COMPUTER

One of the "Operating Systems of the
Future" is now available for the "little
old Color Computer"; OS-9. Freely
translated, OS-9 means "Operating System
for the 6809" (OS-9 is now being written
for the 68000, also). Since it is fairly
obvious that UNIX and "UNIX-Type"
Operating Systems will be running on just
about every computer to come out in the
next few years, a whole new language is
beginning to appear on the horizon.

Color Computer OS-9; the Package

We had been running a preliminary release
of OS-9 on the Color Computer for a few
weeks, and received the "Official Radio
Shack" version for Review a couple of
days ago. To put it mildly, this package
is IMPRESSIVE! For $69.95 (Radio Shack
Catalog Number 26-3030), you receive a 9

System software may or may not be flexible to use. but in
either case, it is not often subject to change. As with the
CoCo, BASIC is in ROM format, which does make it a little
difficult to modify. Instead of modifying system software,
usually a deficiency is overcome by someone writing a utility
that provides the needed feature.

The other category, application software, is split into two
areas: generalized packages and specialized packages. For
the purpose of this discussion, we will consider data base
programs, calculator programs, word processing, etc.. to be
in the generalized area. The specific area would include
many financial packages such as Accounts Receivable.
Accounts Payable, General Ledger. Payroll, along with
Inventory, Job Costing, etc.

The generalized packages have strengths in being more
flexible, alowing the user to "customize" to their needs.
Unfortunately, this added flexibility also brings with it areas
of weakness, in that many of the packages arc more difficult
to set up. What becomes common is the sale of specific
"templates" or predefined designs for the general purpose
packages to use. On the strong side of specific packages is
that they can deal with the subject at hand in greater detail

and. in most cases, are quite easy to use. They can include
complex file structures that just aren't avalable with the
generalized programs. However, one of their major short-
comings is that, in most cases, a programmer is required to
make any changes. The amount of expense involved will be
determined by not only the complexity of the changes, but
also how well the programs and system was designed. This
brings us back to what these articles are all about. . . .

The last area of discussion in this month's article will bean
overview of design criteria. Not particularly listed in their
order of importance, the following are our major design
criteria: "maintainability" modiliability, ease of use, ac-
countability, and target system capabilities. Regarding
maintainability and modiliability. in the real world, many
businesses have unique needs in the area of computer soft-
ware requirements. Many of them can be satisfied with
generalized application packages, however, others require
features that can't be accomplished with a generalized pack-
age. So. we look for software that is specific to the needs of
the user.

The typical situation is one where we find something very
close, but not quite right. Assuming this from the beginning,
we should design maintainability and modifiability into our
programs. I adhere to the "KISS" philosophy: (K)ecp (1)1
(S)imple. (S)tupid! We want to design simple "black box"
modules that can be common to any programming, not only
in our modules, but also in our mainline. This will cost us
some space, and so will good variable names and comments
when required, but it can save us many, many hours of

debugging. This lime savings isn't just at
programming time, but also six months
down the road when we again have to
understand what we did. We will also
want to put a lot of thought into the file
structure before we even come near the
programming stage. More on this later.

As was mentioned earlier, we will
assume the responsibility for ease of
use. We may not even know who is
using the software, and definitely do not
want to spend time on the phone with
each user to get them up and running.
This is bad from a public relations point
of view, and also means that valuable
programming or marketing resources
are tied up not doing what they should
be doing. Going one further, we will
assume that even though we will have a
good manual, most users don't really
read the manual as completely as they
should. This isn't a slight on users, it's a
realistic observation made over the past
six years. Therefore, we want to use easy
selection menus and provide as much
guidance as possible within the programs.

As to accountability, this means that
the software should provide some form
of an audit trail. Can we trace what
happened? This is valuable from two
points of view: it is quite helpful in
debugging the programs, and it gives
the user some of the checks and balan-
ces that are required in financial appli-
cations. In this same area, the software
must comply with accepted practices. If
in the financial area, it must not only be
accurate, and provide a method of bal-
ancing, but should in most cases, not
allow the user to get it "out of balance."

Lastly, target system capabilities must
be taken into consideration. If the vast
majority of users have only 1 6K cassette-
based systems, designing for a quad-
drive 64K computer may not be where
it's at. You are better off to re-think the
desired capabilities and come up with
ones that will fit the systems of today,
but designed for easy expansion in the
future.

In the next article, we will get into
more depth on our design, along with
exploring the use of top down design as
a tool to improve our design objectives.

Prospectins The

By H. Allen Curtis

This article, like that ofTomSzlucha in the September
issue ni the Rainbow, deals with the hidden com-
mands of the MC-IO. Tom, in his article, lamented
the MC-IO's lack ol a C.S.I VEM command. To offset this
deficiency, I am presenting herein a short program simulat-
ing such a command. My article was written to act as an
addendum to the MC-IO manual.

There's gold lo be found in the ROM of the MC-IO
computer. Some prospecting with PEEKs reveals three
tables a table of BASIC key words, a table of entry
addresses to ROM subroutines lor each of the basic state-
ments of MC-IO, and a similar address table for the bask
functions. These tables can be found at ROM addresses
57413-57670. 57672-57737 and 57344-57391, respectively.
The information contained in those tables are recorded and
consolidated in Tables I, 2. and 3.

Table I contains the BASIC key words of bask statements
along with their associated ROM routine entrj addresses
and tokens. The addresses and tokens are given in both
decimal and hexadecimal notations. A token is a single byte
thai represents the key word when it is stored in the BASIC
program.

Table 2 contains the basic functions, their ROM entrj
addresses and tokens.

Table 3 contains logical operators, arithmetic operators
and basic words having no ROM routines of their own.

There is some gold dust in Tabic 3: The appearance of [I]
among ihe arithmetic operators indicates accurately that the

MC-10 has the previously undocumented ability to raise
numbers to powers. However, heavy gold nuggets are lound
in rabies I and 2. Table I shows the existence of the EXEC
command, a command not mentioned in the MC-10 man-
ual. Table 2 reveals that there are two functions. USR and
VARPTR. that are also unmentioned in the manual.

The three uncovered nuggets provide convenient means
ol accessing machine-language routines and programs
Finding the three nuggets made me suspect that there might
be more gold hidden in some of the commands described in
the manual. Maybe some of their features were left ttniles-
cribed. Mv suspicions were soon confirmed, 1 found that
appending the suffix M to CLOAD produces a variant of
that command that will load machine language programs.
Moreover, the CLEA R command has facilities for protect-
ing memorv space at the high address portion of the RAM.
where machine-language routines can be POKI.lI.

Unfortunately, the MC-10 has no CSA VEM command to
record machine-language programs on tape. To remedy this
deficiency I have written a program that will simulate a
CSA I'TTjW command. The presentation of this program will
be used to illustrate how the CLEAR and EXEC arc used

Before the presentation is made, it is worthwhile interject-
ing some remarks about machine language programs
and BASIC programs using machine language routines.
Sooner or later you will probably encounter problems
whose solutions require programs that must execute with
speeds and economy of memory usage which cannot be
achieved with basic alone. Machine language programs can
provide maximum execution speeds and memory economy.
However, such programs are usually complex and much
more difficult to write and debug (locate programming
errors). Often the best solution is a BASIC program with a
lew strategically chosen machine language routines. Such a
program combines the simplicity of BASIC and the speed and
economy of machine language.

It is hoped that this article will stimulate the use of
machine language programming. Writing machine language
programs and routines requires familiarity with assembly
language programming and the 6803 microprocessor's in-
struction set. Towards gaining this familiarity, it is sue
gested that you read "BASIC Microprocessors and the 6800,"
Ron Bishop. Hayden Book Co., 1979,

In Listing I is shown the program for saving machine
language programs, Using the CLEA R command, the pro-
gram protects the final 53 bytes of the MC-10 RAM. Then it
POKEs 53 bytes comprising the machine language program
into the protected memory area. This memory area is pro-
tected in the sense that the memory areas for the BASIC
program, its associated variables, and the BASIC stack will
not encroach on the protected RAM. After the machine
language program is POKEd into high RAM. the EXEC
command provides a means of entry from BASIC to the
machine language program.

In line 10 of Listing I, the first address of the protected
memory area is calculated. The number, 256*PEEK( 16976).
is the highest RAM address minus 255. The address given bv
X inline 1(1 is 20427 for a 4K byte RAM or 3681 1 lora20K
byte RAM. In hnc20CLEAR100, X-l reserves lOObytesof
string memory and protects all memory beyond X-l. I he
CLEAR command also initializes all variables Hence, the
first address of the protected RAM, which also happens in
be the entry address of the machine language program, musi
be recalculated in line 30.

Line 70 is included to prevent the execution of the
machine language program when one or more of the DA TA
Statements of lines 90 through 170 have been typed incor-
rectly. In line 80 EXEC X initiates the execution of the
machine language program at the entry address X.

When you have keyed in the program without any typ-
ing errors and run it. you will see a question mark (?)
prompt and a flashing cursor. For the present, ignore the
prompt and press [BREAK], CSA VEths program on tape
for future reference. Then rerun the program and answer the
prompt by typing in decimal the first address of the program
to be saved, then its last address, next its entry address, and
finally a filename. The typing format is as shown in the
REM of line 5. A comma must follow each address, and the
filename must contain eight or less characters enclosed bv
quotes. The three addresses for the machine language pro-

However, frequently to reduce memory consumption it

gram now residing in the protected high
RAM are 20427. 20479, and 20427,
respectively, for a4K RAM and 3681 1,
36863 and 368 1 1 , respectively, for a 20 K
RAM. CSA VEM is an appropriate file-
name for the program.

After typing the addresses and file-
name, pressing [ENTER] initiates the
recording process. Therefore, before you
press [ENTER], be sure that you have
properly positioned your the tape and
have depressed the record and play but-
tons of your recorder. If you make a
typing mistake, you may get an error
message instead of recording. In such a
case, use EXEC again and repeat the

process.

When you have a good recording of
the program, CSA VEM. turn your
computer off and then on again. Now
with an empty RAM you can use the
CLOAD M command to test whether or
not CSA VEM works properly. Before
loading, protect the top of the RAM for
CSA VEM by typing and entering the
following:

CLEAR !00,256*PEEK(I6976)+202

Then type CLOADM"CSA VEM" if
you rewind to the beginning of the tape,
or merely use CLOA DM \f you position

the tape between the two programs
recorded. Then press [ENTER] and you
should shortly get the OK prompt. To
make entry to CSA VEM. merely type
£A"£Cand press [ENTER]. CLOADM
provides the entry address.

There is another interesting feature of
the CLOADM command that has
facilities which allow you to load a pro-
gram in different portions of the RAM.
Using CLOADM with the format —
CLOA DM "filename".n — where n is a
decimal address offset, you can load the
program into an area whose first address
is n greater than the recorded first
address of the program. To load the
program into an area whose first address
is n less than the recorded first address,
you must use 65536-n instead of n.

To see how this feature works, try
loading CSA VEM at a memory area
from 19427 through 19479 for a 4K
RAM or from 3581 1 through 35863 for
a 20K RAM. Before loading. PEEK at
the contents of 19427 or 358 1 1 depend-
ing on the size of your RAM. That is,
type and [ENTER] either: PRINT
PEEK( 19427) or PRINT PEEK(358I I)
respectively. Remember this number
for future comparison with the contents
of that address after loading. Position
the tape for loading. Then type CLOA DM
"CSA VEM ".645 36 and press [ENTER].
Depress the play button. After the OK
prompt appears, PEEK at the contents
of 19427 or 35811 again. If the address
now contains 206. you have verification
that the offset feature of the CLOADM
command works as described. Entry
can be made by means of EXEC as
before.

This feature of CLOADM must be
used with caution. The program to be
loaded must be relocatable, that is, it
must have the ability to execute prop-
erly regardless of its location in RAM.
CSA VEM was purposely written to be
relocatable for your convenience and
the safe application of the CLOADM
offset feature.

Machine language routines that are
integral parts of a BASIC program can be
stored in protected high RAM. How-
ever, frequently to reduce memory con-
sumption it is convenient to store ma-
chine language routines in strings. Once
a machine language routine is "packed"
in a string, the READ-DATA-POKE
sequence of instructions can be deleted
from the basic program. These dele-
tions can be safely made because the
machine language routines are embed-
ded in the BASIC program and will be
loaded as a part of that program.

The VARPTR function is often used to determine the first
string address into which to POKE the machine language
routine as well as to provide the entry address. The program
of Listing 2 is the same as that of Listing I except for lines 10,
20 and 30. Therefore, load the previously saved program of
Listing I and type in the new lines 10, 20 and 30.

The five sequences of 1234567890 followed by 123 in the
string AS of line 10 provide the needed space for the 53 byte
machine language routine. If you type more or less than 53
characters into AS, then the program will stop at line 20. In
line 20, B=VARPTR(A$) is the address containing the
number corresponding to the length of string AS. In line 30,
X is the address of the first character in the string AS.

When you have completed typing and entering lines 10. 20
and 30, run the program. Break out of the question mark
prompt and notice how string AS has changed in line 10.
Don't worry, this colorful but unintelligible representation
of the machine language program is correct. Delete lines 40
through 70 and lines 90 through 1 70. Now, you have a short
BASIC version of the program to save machine language
programs. Save it on tape.

It should be pointed out that strings may not be packed
with any byte having a value or 34. The ASCII code that is
provides the end of BASIC line signal, and 34 is the ASCII
code for quotes. Note that DATA statements 90 through
170 did not contain any 0s or 34s.

The EXEC command is limited in scope compared with
the USR function. The USR function not only provides
means of entry to and exit from machine language routines,
but also is the mechanism for passing information back and
forth between the BASIC program and its machine language
routines.

The program of Listing 3 is used to illustrate the workings
of the USR function. The machine language routine is
POKEdmlo the string AS of line 10. The machine language
routine performs the arithmetic function SQR(ABS(2*
INT(N))) where N is a number that you enter in response to
the INPUT statement of line 100. Ordinarily you would
employ BASIC programming to perform the aforesaid
arithmetic function. There is no real advantage doing it in
machine language. The routine was written solely to illus-
trate USR function properties.

VARPTR is used to determine the address of the first
character in the string AS. In line 30, M is the most signifi-
cant byte of the first address of the machine language rou-
tine, L is the least significant byte of that two byte address.
The first address of the routine is also its entry address.

In line 90 the two bytes of the entry address are POKEd
into addresses 16918 and 16919. In Table 2 note that the
entry address for the USR function is 16917, a RAM
address. At 169 1 7 is the operation code for the 6803 micro-
processor's JUMP (J MP for short) instruction which is
analogous to Basic's GOTO. The POKEmg done in line 90
allows the USR function to make entry to the machine
language routine.

The value of the variable N in the USR function of line
110 is the information that is passed from the BASIC
program to the machine language routine. Each of the lines
130 through 1 70 contains a 6803 instruction which after the
READ- DATA -POKE sequence is packed into the string
AS. The 6803 instructions are usually represented in either
hexadecimal or mnemonic forms rather than in decimal.
Table 4 shows the five 6803 instructions of the machine
language routine in their hexadecimal and mnemonic forms:

BD EB CA

JSR FACTO D

ASL D

BD EC E3

JSR DTOFAC

BD F2 D5

JSR ABS

7E F5 4D

JMP SQR

The mnemonic forms provide abbreviated descriptions of
what the instructions do. Therefore, they are the easiest
forms to use in programming. The JSR instruction, for
instance, is analogous to Basic's GOSUB command. JSR is
a jump to a machine language subroutine. FACTOD in JSR
FACTOD is a label assigned by the programmer to the entry
address of the subroutines. The label describes what the
subroutine does. In this case, the subroutine transfers the
value of N from BASIC'S floating point accumulator to the
6803 microprocessor's accumulator D. In the process of
making the transfer the value of N is converted into an
integer. The instruction ASL D does an arithmetic shift left
one bit position of D, which is equivalent to multiplying the
contents of D by two. JSR DTOFAC transfers the contents
of Dto FAC. JSR ABS makes the number in FAC positive.
Note the address, F2D5, corresponding to the label ABS is
precisely the entry address of the ROM routine for BASIC'S
ABS function given in Table 2. Finally, JMP SQR causes
the square root of the contents of FAC to be taken and
returns the result to BASIC. The address F54D correspond-
ing to the label SQR is also found in Table 2. As you might
suspect, Tables 1 and 2 furnish valuable information to the
machine language programmer.

In general, the information passed from BASIC to a
machine language routine is stored in FAC. When you
wish to perform integer arithmetic on the passed informa-
tion, you must transfer the contents of FAC to D. Hence,
JSR FACTOD should be a very frequently used instruction.
The final contents of FAC are the value that gets returned to
BASIC. The final instruction used to exit from a machine
language and return to BASIC is always RTS (Return from
Subroutine and is 39 in hexadecimal form). This statement
seemingly contradicts the fact that the machine language
routine associated with the program of Listing 3 ends with
JMP SQR. Each ROM subroutine is terminated with an
RTS. Using JMP instead of JSR makes the SQR subrou-
tines' RTS exit the return to BASIC exit.

It is hoped that you will manufacture many beautiful
golden objects with the ore mined in this article.

WITH UTILITIES

COLORKIT

We are proud to announce that the
COLORKIT, written by George Zinowitz,
and formerly marketed by Arizin Inc. of
Scottsdale, Az., is now one of the broad
line of Prickly-Pear Software utilities.

This programer's aid is truly an amazing
program. First the small stuff. With the
COLORKIT you have your choice of light
or dark screen, and you can have a key-
click if you like. You can easily disable the
BREAK key also, and you can slow your
listings down to a readable speed.

In addition, you get an outstanding FULL
SCREEN EDITOR while retaining the
standard editor. You can list all the vari-
ables currently being used in a program.
You can merge machine language pro-
grams and BASIC programs into a single
unit that can be saved or loaded easily.
You can do a global search through your
program for any target you specify. You
can easily examine or move sections of memory. You can echo all screen output to the printer.
You can easily recover a program lost because of a NEW, BACKUP, orDSKINI command. You
can print the addresses of the last machine language program cloaded. You can get a help file
on the screen showing all commands. You can program 10 function keys with up to 250
keystrokes each.

Whew!! We're running out of breath, but you can believe we are not running out of features!
The incredible thing is that all of these functions are easy to use. They are accessed by simple
one word commands. What the program really does is add a lot of commands to BASIC that
should be there but aren't. Did you type NEW by mistake? No problem —just type .OLD and
the program is back! The other features are just as easy to use. The program comes with a 20
page manual which fully explains all of the features.

This program is about 6K long and is 1 00% machine language and 1 00% relocatable. It runs

in computers 1 6K or larger. If you have 64K you can put it up high, and it uses no BASIC space

at all. The same program will work equally well on disk or non-disk machines. Step up to the

program that REALLY extends your BASIC, and take full advantage of all the great

programer's tools you've been missing. On tape — $34.95. Same program on disk —

$39.95.

Programs are available on AMDEK cartridges - add S5.00

OS-9 Meets

The Wolf bug
Monitor

The Wolfbug monitor program, sold by Atomic City Electron-
ics, is a handy machine language utility for the 64K CoCo
owner. It furnishes memory, examine/ change, ASCII dump,
and other functions common to most monitors, and also has com-
mands for switching into the 64K RAM mode and for transfer of
BASIC into RAM. The monitor is supplied in a 2716 EPROM that's
used in a special circuit board which plugs into one of the BASIC
ROM sockets. The EPROM re-
sides in memory space between

SF800 and SFFFF, with the chip-
select provided by on-board gates
connected directly to CoCo's ad-
dress lines. A "decode defeat"
signal disables the 74LS139 de-
coder in the computer so that
addresses inside the $F800-$FFFF,
that address range is therefore
effectively removed from control
of the SAM chip.

When the computer is used in
the32K RAM-32K ROM mode,
there's no problem, because the
addresses that Wolfbug occupies
aren't otherwise used. However,
in the 64K RAM mode, the over-
riding of the SAM's control means
that you lose the use of the RAM
between SF800 and SFFFF. Un-
fortunately, that's where the ker-
nel program of the new Radio
Shack version of OS-9 resides, so
attempts to boot OS-9 will crash
a Wolfbug-equipped computer.

What's needed is a way to
switch Wolfbug in and out of the
memory map, so that it can be
turned off easily before booting
OS-9. Fortunately, that is easy to
provide. A single pole, double-

so that it can be turned

OS-9. Fortunately, that

throw switch will let you choose between
Wolfbug and OS-9.

The circuit diagram supplied with the
Wolfbug kit shows that there are several
places to interrupt the address decod-
ing. The circuit board is provided with
wire jumpers that allow the selection of
either a 2K (2716) or a 4K (2532)
EPROM. It is supplied from the manu-
facturer configured for 2K, but the
jumpers are available if one wants to
change the circuit. Probably the easiest
way to disable Wolfbug is to remove the
jumper connected to pin I of the74SL10
and switch pin I to ground. That chip
contains 3-input NAND gates, one of
whose output forms the EPROM chip-
select signal. Grounding any NAND
gate's input freeezes the output in the
"high" stale regardless of the condition
of its other inputs. Pin I is switched
back to its original connection to re-
store Wolfbug to the memory space.

To do it, refer to Figures 1 and 2, and
follow the steps given below. Inciden-
tally, on the circuit diagram included
with my unit, the connections to pins I
and 2 of the 74LS 1 were reversed from
the ones actually on the circuit board.
The instructions given below are con-
sistent with the actual circuit. Both pins
I and 2 are inputs to the gate that gener-
ates the EPROM select signal, however,
so it wouldn't make any difference which
one you switch to ground.

1) Remove the computer's cover and
set it aside.

2) For computers having the "E"
revision circuit board or earlier, the
Wolfbug board is located under the RF
shield. If that is the case in your machine,
gently pry off the RF shield. Carefully
pull the Wolfbug circuit board straight
up and out of its socket. Turn the board
upside down, being careful not to dam-
age the wires attached to it.

(Dr. Bill Clements, a professor of chem-
ical engineering at the University of
Alabama, designs peripherals and pro-
grams for his department 's student com-
puter facility [all Co Cos]. His major
interests are in process control and
microcomputer applications.)

3) Locate the short jumper wire that
is connected between the outside holes
of the three pads below the 74LS10, as
shown in Figure I. Unsolder both ends
of the jumper wire and discard it. Solder
a piece of wire-wrap wire about 8 inches
long into each of the two holes where
the original jumper went. Pass the wires
under the RF shield (if your Wolfbug
hardware is installed there).

4) Identify the wire going to the
right-hand hole in Figure 1 . That is the
wire that connects to pin I of the
74LSI0. Solder the free end of the wire
to the center contact of a miniature
single-pole, double-throw toggle switch
(such as Radio Shack 275-613). Solder
the free end of the other wire to either of
the outside switch contacts.

5) Solder another 8" piece of wire to
the remaining outside contact of the
switch. Solder the free end to a conven-
ient ground point, such as TP3 or TP4
(for "E" boards and earlier), or TP2 or
TP8 (for the newest board revision).
The final connections should appear as
in Figure 2.

If you'd rather not saw on your cover
(and remove the label on the channel
switch in the process) you can drill a
hole for the Wolfbug switch in the top
cover at any free spot that the wires will
reach, and mount the switch right in the
cover. If you do it that way, just be sure
not to forget it's there and break off the
wires the next time you pull off the
cover.

Label the switch function, using a
small stick-on label applied to the case
next to the switch. Most toggle switches
connect the center contact to the outside
contact that is opposite the handle.
Turn on the computer and see in which
position the command EXEC 64000
brings up Wolfbug; label that position
"WOLFBUG ON." If the machine
crashes, turn if off and label that posi-
tion of the switch "WOLFBUG OFF."

Now, when you get ready to run OS-
9, just check the position of the switch
before booting. When you want to use
Wolfbug in non OS-9 applications, it'll
be available just by reversing the switch.

KISSABLE OS-9

Point, Counterpoint, Termina

Problems And A
Technical Potpourri

By Dale L. Puckett
Rainbow Contributing Editor

Tandy's OS-9 for the 64K CoCo hit the shelves in early
November. The phone calls and letters, filled with
questions and signs of frustration, started coming
soon thereafter.

I got my first look at a production copy of OS-9 at a Radio
Shack store in Elizabeth City, N.C. 1 had a few free minutes
one evening while in town attending a week-long pollution
response course presented by the U.S. Coast Guard Atlantic
Strike Team. I was very impressed with Tandy's profes-
sional packaging and the quality of the documentation. Yet
OS-9 is so complex and powerful that it's going to take
everyone some time to learn the ropes. That's the bottom
line.

1 remember the first month I used OS-9 — 1 really
stumbled around. I had used FLEX for three or four years,
but OS-9 was a whole new ball game. 1 didn't understand
what was happening. The error messages didn't make any
sense. But in a week or two, things began to clear up and I've
never gone back. Soon, 1 found myself taking the multi-
tasking; the handy "hierarchical directories; the fast random-
access files; the type ahead buffer; the "pipes" and the rest of
OS-9's friendly environment for granted.

We're going to take a different approach to KISSable,
OS-9 this month. We'll answer as many of your questions as
possible and try to help you pass through the early part of
the learning curve. First, though, I want to clarify my philos-
ophy to my readers and the fine group of programmers and
software distributors that are working their tails off to bring
professional software to the Color Computer.

(Dale L. Puckett is a freelance writer and programmer
who has worked with the Motorola family ofmiropro-
cessors since 1976. He just completed his first hook. "A
Complete Tour Guide to BAS1C09. "this summer. It is
being published by Microware and will be available
this fall. He is the author of DynaSpell, Readiest,
Esther and Help, which are available from Frank
Hogg Laboratories. He serves on the Info World
Software Review Board and is a Chief Warrant Officer
in the U.S. Coast Guard.)

Michael R. LeVasseurof St. Petersburg, Fla., brought up
a point: "Please limit yourself to the properties of this
remarkable operating system. Let the software reviewers
and Frank Hogg's advertising dollar take up the new soft-
ware issue."

Counterpoint: Sorry, Mike. 1 don't agree. It is not enough
to let my readers depend on advertising copy to figure out
what new OS-9 software products do or how they work.
Advertising is designed to do only one thing — get your
attention. It is also very one-sided. Only the good points are
mentioned. It seldom explains what a product does and
almost never tells how it works or what it can really do for
you. Unless a reader really knows and understands software,
he is making a long leap of faith when he buys most new
packages.

Further, I feel the high resolution display described last
month is a major product. It makes OS-9 a usable and viable
package. Frankly, it should have been a part of OS-9 itself.

Motorola's 6809 microprocessor is the best eight-bit pro-
cessor on the market. You won't find many programmers or
engineers that will argue with that fact. Yet, because of a
lack of standardization and cooperation between vendors in
the past, it never became a strong force in the personal
computing marketplace. With Tandy's selection of OS-9 as
the operating system for the Color Computer, we now have
a standard and another chance to become a viable force. I
intend to help the 6809 make it this time by explaining every
major product in enough detail that my readers will know
what it is and what it will do for them.

In fact, here's an invitation to all software developers. If
you're developing a new product for Color Computer OS-9.
drop me a line. Put us in your rumor loop and we'll help you
spread the word. When you have the product ready to go, let
us try it and we'll do a play-by-play similar to the article on
Hi-Res in December. A lot of packages never get off the
ground because they're never explained. We'll do our part to
solve that problem with KISSable OS-9.

Now What?

LeVasseur also noted that another magazine had said that
Tandy's OS-9 documentation was well written and easy to
understand. Then he added: "Perhaps so, but I would like lo
do something more interesting than BUILDing files, dis-

324

playing DIR and MAKDIR. (Why would 1 want to MAK-
DIR anyway?) A similar comment came from Bob Dooman
of Glenview, 111. "Okay, I have OS-9, and I understand the
'basic' commands. . . . Now what?"

Let's recap a few of the points 1 made in my first KISSable
OS-9 column. OS-9 is a tool. And as with any tool, you must
learn the basics before you achieve productivity. Before a
baby walks, it crawls. Another good analogy is the coach
that holds blocking and tackling drills for a month before he
puts the first play on the chalkboard.

Each utility program in your OS-9 CMDS directory is a
tool and most of them work on files. Before you can work on
files, they must exist. BUILD is nothing more than a handy
utility that makes it easy for you to put small files on a disk
so you can use them in the future.

These files may take the form of simple text which you will
list to your screen later when you need a reminder. Or. they
may be "procedure" files that automatically run your CoCo
through a series of small programs that together do a big
job. In any case, before you can use them, you must get them
on the disk. Hence, BUILD.

For larger files you will want to use a larger editor to enter
your text or procedures. Microware 's EDIT, which comes
on your OS-9 system disk, is an excellent line editor. If you
prefer a screen oriented editor, DynaSiar is excellent.

DIR is also a necessary evil. Granted, you can print the
names of your files if you only have one or two on a disk.
But, what happens when you have a dozen? And even if you
do remember their names, can you remember how you
spelled them when you made up the filenames?

Now, let's justify MAKDIR. Remember what it was like
when you were running Radio Shack's Extended Disk
BASIC? Everytime you typed DIR, the names went by on the
screen like a fast freight. If you had nimble fingers, you
could stop the listing with the [SH1FT][@] combination. It
never worked for me. Every time I tried it, the listing would
stop just after the name I needed scrolled off the top of the
screen.

Even FLEX's CAT ox DIR commands could be a prob-
lem. FLEX is a great operating system and it has a feature
which causes the scrolling to stop each time the screen fills
with text. But did you ever do a C4 7"on an eight-inch disk
with 500 files? There must be at least 50 filenames that start
with every letter in the alphabet on every one of my drives. It
takes a lot of time to look at them all, just to find the
command or text file you want.

Enter OS-9's "hierarchical" file structure. Let's use another
analogy. How is your office set up? In most businesses, each
person has a desk and an individual file cabinet. That
cabinet is divided into drawers which contain information
relevant to a specific part of that person's job.

Now, let's automate the office. We'll use a microcomputer
with an operating system that lets several people work on
different terminals at the same time. That sounds like OS-9.

If we were using an operating system like Disk Extended
BASIC, everyone's files would be in the same directory — the
same file cabinet so to speak. If a secretary needed to find a
file for her boss, she would have to look through every file on
the hard disk. It would belike looking through every drawer
in a large file cabinet. It would take her a longtime. The boss
would get angry.

OS-9 solves this problem by letting you use multiple
directories. Let's go back to the same office and show that
the same hard disk would look like if it were running under
OS-9.

For starters, it would have a device name, probably
"/HO." When the secretary does a DIR of the drive it proba-
bly looks something like this:

DIRECTORY OF 12:32:30

OS9Boot CMDS SYS DEFS

Startup Read.This BOSS SECRETARY

SAM JOE SALLY JANE

If she did a DIR with the "e" option she would notice that
each of the filenames above that were printed on the screen
with all capital letters had a "d" printed in the Attributes
column. This means it is a directory. Typing directory names
in all capital letters is one habit you'll want to pick up early
in your OS-9 career. It'llsaveyou from losing your hair with
a lot of head scratching.

Now, let's suppose that the file the boss wanted to see was
a letter that Sally had sent to the company's ad agency last
week. Our trusty secretary could then type:

OS9:chd../ SALLY
OS9: dir

At this point, she might see something like this:

DIRECTORY OF 12:32:45

ADVERTISING NEWSLETTER PAYROLL

SCHEDULES ACCOUNTS.PAYABLE

Since she knows that each of the filenames listed are
directories she then types:

OS9: dir advertising

She may see something like:

DIRECTORY OF advertising 12:33:02

COPY IDEAS

Instructions

Now, she can type:

Agency. Letter

OS9: list advertising/ Agency. Letter >/p

You have just seen how easy it is to find a file when it has
been stored in a logical place. Our secretary knew that Sally
wrote the letter so she looked in Sally's directory. Since she
knew it was to an advertising agency, she looked in Sally's
advertising directory. She had the boss' answer in seconds.
Looking through hundreds of filenames on a single hard
disk directory would have wasted a lot of time. That is why
you "would ever want to MAKDIR."

Now What, Continued

Now, let's tackle Bob's question. First, we must under-
stand that OS-9 itself is only an operating system. It is not an
application package or a language used to write programs. It
is, rather, an environment that provides a home for youv
languages and applications. As we stated in December, it
was written to provide the support necessary for BASIC'09, a
state of the art language designed by Microware and
Motorola.

Yet, OS-9 comes with nearly 50 utility programs that can
do manyjobsforyou. With the addition of a toolbox like the
one library of file handlers sold by Microware, you can do
many jobs right from the OS-9 command line. We gave you
a few examples in our January column. Here's another
example of what you can do with an understanding of this
operating system and a little imagination.

February 1984 the RAINBOW 325

How many times have you wanted a simple database
manager that would let you look up a phone number fast?
Try this:

OS9: BUILD phone

? ken kaplan, 515-555-1212, des moines, ia
? lonnie falk, 502-228-4492. prospect, ky
? jim reed. 502-228^492. prospect, ky ?

This sequence of lines uses the BUILD utility to place
three names with the proper telephone number, city and
state, in an OS-9 text file. Of course, you could put hundreds
of names and numbers in a file with one of the larger editors.

Now, suppose that you are on the phone and someone
asks you for Lonnie's number. Your desk is a foot high in
litte yellow telephone slips and someone has taken his card
from your card file index. What can you do? If you have a
CoCo running OS-9 on your desk and have installed one of
the UNIX like toolboxes, you can simply type:

OS9: grep Lonnie phone

In a second or two this line will appear on your screen:

lonnie falk, 502-228-4492, prospect, ky

Let's give another example. What can you do if you
remember a long lost friend in Kentucky that used to talk to
you on the ham radio bands, but you can't remember his
name? Try this:

OS9: grep ky phone

Seconds later you'll see this message on your screen.

lonnie falk, 502-228-4492, prospect, ky
jim reed, 502-228-4492, prospect, ky

How's that for an easy and cheap electronic phone book?

Terminal Problems

The one problem that has prompted more calls than any
other has surfaced when readers have attempted to hook up
an external terminal to CoCo's RS-232 connector and use it
as device, /Tl.

I tried it last August when 1 first installed OS-9 on my
computer and it seemed to work. But, since I was receiving
so many calls. I thought I better check it out again. So this
weekend. I tried it again, twice.

The first time I used my GIMIX computer running a
mode program as a terminal for the CoCo. Talk about

overkill. When it didn't seem to be as reliable as I thought
necessary, I decided to hook the Televideo Model 925 up
directly to CoCo. 1 wanted to be certain that I did not have a
problem with my modem program or with the configuration
ofthe ACIAs on the GIMIX.

After a quick trip to the local Radio Shack for a DB-25
RS-232 connector for the Televideo. I made a cable and
tried again. Same results.

At this time, I started to experiment with Baud rates. It
turns out that device ,'T1 in CoCo OS-9 is almost reliable at
600 Baud. If you try to run it at 1200 Baud, it will not work at
all. The 300 Baud position seems to be solid, albeit painfully
slow.

Unfortunately, it seems that if you want to run an external
terminal, you must use a transmission rate no higher than a
300 Baud. Also, I noticed that it is impossible to halt a listing
on the external terminal. The wait, interrupt and abort keys
simply do not work. All of these problems are caused by the
"bit banging" routines that try to make a PIA look like an
ACIA to the outside world. Hopefully, the new RS-232 cord
that is designed to plug in the new expander interface con-
tains a real ACIA. If so, it will be easy to write a device
descriptor and device drivers to use it.

A Higher Stepping Rate Boot

We promised to give you this information last month but
somehow it managed to slip through the cracks. Before we
start though, we should clear up a related question for J.
Frank Fields of Bethany, Okla. The typesetting machine
moved two periods too close together and threw him a
curve. He writes: "I couldn't follow your directions after
DB:L CCDIS. I had to use DB: .BE00+204 or single step to
the location, otherwise all was very successful."

Here's what the sequence should look like:

that module, BEOO, and the value of the byte stored there,
87. Your next line tells DEBUG that you want to add 204
hexadecimal to your present location (BEOO). It docs this
and returns a value of hexadecimal C004. This is where one
of the magic mystery bytes that changes the drive stepping
rate is located. Actually, the value you changed above is the
value of a constant used in a delay loop.

Frank found another typo on Page 163 of theOS-9 Pro-
gram Development booklet. So you won't have the same
problem, here is the correct sequence:

OS9: cobbler /dl

OS9: verify </da/os9boot >/d0/tempu

OS9:del /dl/os9boot

OS9:copy /dO/temp /dl/os9boot

To make a disk that with the higher stepping rates that
will boot, perform the following patches using DEBUG:

OS9: debug

INTERACTIVE DEBUGGGER

DB: 1 boot

FD74 87
DB: . [SPACE] ,+A9

FE1D43
DB: =41

FEIE34

After you have patched the byte above, link to the boot
module again, ie, 1 boot, and make the following changes:

OFFSET OLD NEW

B5 03 01

154 13 II

15A-I5B 222E 082B

Note that each of the offsets above is from the start of the
module and is found by using DEBUG's "I "command.

After you have made the changes you must save the new
boot module to a disk file:

OS9: save /dl/tempboot boot

Then, you must verify the disk file you have just saved to
find (he proper CRC for the file:

OS9: verify </dl/tempboot >/dl/ updated. tempboot u

Now, the CRC bytes in the file /dl/ updated. tempboot
will be correct. Examine them with I DENT or use DUMP to
list them to the screen and write them down. Then, use
DEBUG to change the CRC bytes in the"boot"modulcthai
you changed in memory. The CRC bytes in memory MUST
agree with the CRC bytes in the verified file, "updated. -
tempboot." The CRC bytes are the last three bytes in the
module. After you make this modification, you can use
COBBLER or OS9GEN to make a new boot' disk. Don't
forget to save the changes you made last month in the
CCDIS module.

Faster Speeds And 40 Tracks, Too!

J. Frank Fields also asked how to set up CoCo OS-9 to
use his 40-track drives.

This modification is made in the device descriptor module.
/D0and/Dl are both device descriptors. Hence, if you have
40-track drives installed as both devices you must change
both drive descriptors. Here's the sequence:

OS9: debug
DB: I dO

C10B87
DB: .[SPACE] .+ 18

CI 23 23
DB: =28

CI2401
DB:q

After you change this byte in the device descriptor /dO,
OS-9 will know that you have 40 tracks available on that
device. Repeat the sequence of steps above on the device
descriptor /dl.

Once you have changed the device descriptor, you may
use the COBBLER command to create a disk that will come
on line with 40-track drives for /dO and /dl.

After you make this modificaton, OS-9 will still read and

write to disks that were formatted earlier with 35 tracks. You

must format a new disk using the format utility — after you

have made this change to the device descriptor (/ DO or / D 1 )

- before you can actually use 40 tracks.

A BASK09 Tip

My sources tell me that BASIC09 is now (December 1) on
the shelves. I have also confirmed through a second source
that Microware's C is hot on its heels. Tandy should have it
soon after you read this. You're going to love the day you
bought your CoCo.

Since BASIC09 is on the air, next month we'll try for an
in-depth intro of this fascinating language.

Should you type your BASIC09 programs using uppercase
letters? Or would lowercase letters look better'.'

Most programmers will agree that BASIC programs look
nicer and arc easier to understand when BASIC keywords are
typed in uppercase letters and variable names are typed with
lowercase letters. With many languages, this is quite a has-
sle. It's a snap with BASIC09.

Here's how to go about it. When you type a procedure,
leave your keyboard in the lowercase mode and only use the
shift key when you want your procedure to print a capital
letter. BASlC'09's buijt-in editor will do the rest. When you
list the program you'll be in for a nice surprise.

In fact, you'll see that BASIC'09 does more than capitalize
keywords. It also automatically indents listings. This makes
procedures easier to read and will help you find certain
logical errors.

Here's an example. If you type:

for count := first to last
print count

BAS1C09 will list it like this:

FOR count := first TO last

PRINT count
NEXT count

We'll try to pass along little hints like this on a regular
basis as part of KISSable OS-9.

Inclosing, I would like to correct a false impression stated
by Shncor Z. Sherman of Davis, Calif. He wrote to ask why
anyone would want to run OS-9 and BASIC09 since BASICQ9
doesn't have any graphics capability.

Far from true, Shneor. With OS-9, even the operating
system has graphics capabilities. It would be a very easy
matter to BUILD a procedure file using the DISPLA Y
utility and produce all kinds of attractive graphics on
CoCo's screen. Maybe we'll try that next month! Till then!

TURN OF THE SCREW

Trouble Shooter Makes
Program Pak Connection

By Tony DiStefano
Rainbow Contributing Editor

I would like to get right into business this month. The first
thing I want to discuss is about telephone calls. I was
good enough to give out my number to those people who
had problems with my projects or want to express an idea or
opinion and 1 think that it is great that I got a lot of response;
but please limit your calls to Monday nights only! For those
of you who do not have my number and those of you that
just started getting the Rainbow, my number again is (514)
473-4910. Call only after 7 p.m. EST and not too late. I am
an early riser!

Okay, now back to the order of the day (month?). One of
the best things to come out of these phone calls is that people
can point out errors in my articles. (Yes, I do make mistakes.
You should see my replacement-parts bills.) The faster I
know about the mistakes, the faster 1 can write a fix for
them. The main reason for the mistakes or errors is the
transfer of information from my proto-board to you, the
Rainbow reader. All of my projects are tried and tested
before I write them in here. If a project that you put together
does not work, check your work carefully. If it still doesn't
work, call me and I'll give you a fix. If I can't give you a fix
on the spot, I'll write one up in the following article.
Speaking about fixes, here is one.

There is a problem with my internal speaker/ amplifier
project. The capacitor marked C-2 in the parts list is wrong.
It is not a .022 uf capacitor. It should be a .002 uf capacitor.
Also, the part number for the LM-380 (IC-1) is not 276-076
like it says in the article, but 276-706. Sometimes my fingers
get carried away. The last thing to mention is a misprint in
Figure 1. The little scribble to the right of C-2 should read
"6." That is pin #6 of the IC. I would like to thank Hilton
Wasserman for pointing this out to me. For your interest,
the schematics in "Turn of the Screw" are drawn with the
help of my Color Computer and an EPSON printer. I use
the program Schematic Drafting Processor, currently being
distributed by Spectrum Projects. See the ad in this
magazine.

1 received a letter from Kyle Rogers this month, this is a
part of it; "... I enjoy reading 'Turn of the Screw.' and 1
would like to build many, if not all. of the projects presented.
But I find that I have neither the tools, skills, nor the time to
construct the devices. Many hardware columns in other
magazines have alleviated this problem by making an

Color Computer hardware projects. He is one of the
acknowledged experts on the "insides" of CoCo.)

agreement with an outside company for that company to
manufacture and market pre-assembled versions of the
projects presented in that magazine. . . ."Can anyone help?
Please contact me through the Rainbow.

The remainder of this article will be in answer to Tewfick
Chidiac's question, "What do all the pins in the Program
Pak connector, on the side of the computer, connect to,
anyway?" Okay, Tewf, here is a detailed description of the
Program Pak connector.

First of all, the main use for this connector is to plug in
(you guessed it). Program Paks. These are little plastic cases
that contain a small PCB (Printed Circuit Board). On this
PCB these is usually one or more ROMs (Read Only
Memory). This is where the game or utility software is
stored. Other examples of different types of Paks are; disk
controllers, RAM (Random Access Memory) boards, print-
er ports, 1/ O (Input/ Output) boards, serial communications
boards and so on. They all have one thing in common. They
access the "bus." A bus is a term used to represent common
wiring that connect to many components. Having access to
the bus lets you expand the capabilities of your computer.
The bus in the Color Computer fall into three main
categories; data lines, address lines and control lines. Our
computer has eight data lines, it is known as an 8-bit data
bus. It also has 1 6 address lines and several control lines. The
following is a list of all the lines (or pins) that come out of the
connector.

Device Disable Input

I shall describe each pin in detail and where it connects to
inside the computer. I) This output pin comes from the
power supply. It supplies -12 Volts to any component,
maximum drain is 100 ma (miliamps). 2) This output pin
also comes from the power supply. It supplies + 1 2 Volts and
has a maximum of 300 ma. 3) The Hall line is an input line
that goes directly to the CPU. It is lied to normally HI (+5v),
by a resistor of 4.7k ohms. When this pin goes low, the CPU
completes its last instruction and goes into the tri-statc
mode. Tri-state means that all of the CPU bus lines are high
impedance. They are neither HI nor LOW. It is as if nothing
was connected to it. 4) The NMI input line goes directly to
the CPU. It is also tied HI. When this line goes low, the CPU
performs a non-maskable interrupt. That means that the
CPU will jump to a predetermined address and continue to
execute this code until it reaches an RT1 (Return from
Interrupt), in which case it will continue doing what it was
doing before the NMI line went low. 5) The RESET line
connects to the CPU and all the man chips that have reset
lines. All except the VDG chip. That is only controlled by
the external [RESET] switch in the back of the computer.
The function of the RESET line is to initialize all the
components to powerup conditions. U nder software control,
if the value in byte # 57 1 ( 1 1 3) is not equal to S55 ($ denotes
Hex), the computer will do a cold start. If it is, it will attempt

to do a arm start. This line is also tied HI, but ith a 1 00k ohm
resistor. 6) The E clock is the main timing for the CPU. The
E clock is generated by the SAM (Synchronous Address
Multiplexer) and goes into the CPU and nto the bus. 7) The
Q clock is the secondary clock. It is also generated by the
SAM. The Q clock leads the E clock by 90 degrees. 8) This
input goes into one of the PlAs (Peripheral Interface
Adapter). It is tied HI with a 10k ohm resistor. The function
of this line is to detect the presence of a Program-Pak and to
jump to it. 9) This output pin comes from the power supply.
It supplies +5 volts to any component with a maximum of
300ma. 10-17) These eight DATA pins provide bi-direc-
tional communications between the CPU and the system.
They connect directy to the CPU and all other data related
chips. 18) The Read/ Write line is an output which tells all
data related chips which direction the data lines of the CPU
are in. 19-31 and 37-39) These 16 pins address lines come
from the CPU and tell all other data related chips, where in
memory the CPU wants to Read ot Write. 32) This output is
a chip select. It comes from pin #12 of the 74LSI38. It is
memory mapped to select memory between SCOOO (49152)
and SFEFF (65279). This is a I6K block of memory known
as the cartridge memory or the Color Disk BASIC ROM area
if you have a disk drive plugged in. The pin is active LOW.
which mans that the meory chips associated with this pin
will respond when it is low. 33-34) These two pins are ground
returns. All signals are returned to the system through them.
35) This input is connected directy to the sound multiplexor
(MCI4529b) pin #12. With this pin, sounds in the audio
range can be output to the TV speaker. 36) This output is
another chip select. It comes from pin #9 of the 75LS 138. It
is memory mapped to select memory between SFF40
(65344) and SFF5F (65375). This is a 32 byte long block of
memory mainly used for external 1/ O for such devices as a
disk controller or PIAs. The pin is active LOW, which
means that the I/O devices associated with this pin will
respond when it is low. 40) This input is connected to pin 6 of
the 74LSI38. This active LOW pin disables the internal
device selection. This allows decoded but unused sections of
memory to be used by the cartridge hardware.

Now that you know all about the cartridge connector, go
out and experiment but be careful, CPUs and SAMs are
quite expensive.

THE ADVANCED OPERATOR
For The CPU Of Choice: Go CoCo

By Frank Hogg

This is the first installment of a column by the head of mail requests for topics to The Advanced Operator, Frank

Frank Hogg Laboratory on advanced operating systems,
including FLEX, OS-9 and matters of your choice. You may

What is an Advanced Operating System'! Before 1
get into what an advanced operating system is, I
have to give you some history so that you have a
point of reference. Hang on, this won't be that boring. 1 first
became involved with micros in early 1977. My first compu-
ter was called a "KI M 1 ." It had all of I K of RAM and a 2K
ROM monitor. It cost more than the I6K CoCo costs now.
The only "mass" storage was a slow 300 Baud cassette — the
CoCo is 1200 Baud — and the display was a six segment
LED display.

After about six months I was able to get a deal on a TTY
and move up in the world. Now. I not only had a terminal
with real keys, I also had hard copy output. It ran at a
fearsome speed of 1 10 Baud, that's 10 characters per second,
or about as fast as you can type. Pretty bad, but remember
that was 1977. The KIM had a 6502. just like the Apple and
Commodore, but there was no software available for it and 1
became restless for something more.

I picked up a used SWTPC 6800 computer. This was
originally a kit, and the company is still in business today.
As a matter of fact, 1 think it is the oldest microcomputer
company still in business. The SWTPC is a SS50 bus com-
puter, you probably have seen the ads for GIMIX. a well
known SS50 manufacturer. Well, this is what I had as my
second computer. It didn't have an operating system
because ii didn't have a disk, but luckily after three or four
months 1 was able to scrape together the thousand dollars I
needed for a five inch disk system. This system had two
five-inch single-sided single density drives with 340 sectors
of storage each! It doesn't seem like much now, but
remember, back then things were much different. Besides,
we didn't have much to put on the disks anyway!

We finally get to an operating system. The SWTPC had
what can only be called a primitive operating system. It did
little more than save and retrieve information from the disk.
It was not even as sophisticated as RS DOS. You had to
think of the disk as a tape and take care of most of the details
yourself. This meant that you. as the programmer, were
responsible for all the things that todays advanced operating
systems take care of for you. When you think about it for a
while, you can come to the conclusion that after all. this/* a
computer and the software in it should do the work, not you.

Pretend that you had a computer that you could say the
following to:

"Computer, when is my next appointment?"

(Frank Hogg is the president of Frank Hogg Labora-
tory, one of the world's largest suppliers of software
for 6809 based computers. Heancl his wife, Linda, live
in Syracuse. New York.)

and the computer would respond. Well, we haven't reached
that stage yet, but advanced operating systems try to lessen
the need for you to have to deal with your computer at a low
level. The more sophisticated an operating system is, the
better job it will do. There are problems with this though: the
main one being that operating systems are developed before
applications can be developed to run with them. The same is
true for the hardware they run on. The evolution is this: first,
the computer is created, then the operating system, and
finally the applications software. By the time a sufficient
amount of soft ware becomes available for a particular com-
puter, the computer itself is obsolete. This is the case for the
Apple. It has a lot of software available for it. but the design
dates back seven years — to the dark ages.

Of all the 8-bit processors on the market today the 6809 is
the most recent state of the art. It is at year three or so in its
development, and the amount of software available for it
has reached a volume where it is now a practical CPU to
work with. The fact that it is the best 8-bit CPU, and better
than most 16-bit CPUs, doesn't hurt any either. The 6809 is
the CPU of choice to buy today. It just happens to be the one
in the CoCo, GIMIX and several other state of the art
computers available today.

The world is full of "Band wagon followers." If you read
anything today about computers you will undoubtedly
come away with the feeling that if you don't own an IBM or
a "compatible" computer, then you are not with it. People
arc buying on image, not performance in that area, or they
are buying VlC-20s because of price rather than perfor-
mance. Here are some facts for you to digest. The CoCo
running FLEX and TSC Xbasic is three, that's three , times
FASTER than an IBM PC! These timings are from a
benchmark that appeared in Interface Age about one and a
half years ago. The CoCo is not only the fastest micro
around, but the quality of operating system software, both
in FLEX and OS-9, isfar superior to anything available for
any other 8-bit system.

Think of this for a moment. What computer under S3, 000
is multiuser and/ or multitasking? I can't think of any. but do
you know that for under $ 1 ,000, the CoCo with OS-9 is\ Let
me digress for a moment and talk about the importance
OS-9 has on education.

Every college of any value has computers that run with
UNIX! This means that every student that is going to attend
college will have an advantage if they are familiar with
UNIX before they begin college. OS-9 is based on the UNIX
concept, and the transition from one to the other is very
easy. OS-9 is very similar to UNIX, and therefore is ideal for
students to work with. As a matter of fact, we are going to
market a series of programs based on UNIX utilities to
father enhance OS-9 as a UNIX like system.

the RAINBOW February 1984

THE TANDY SCOREBOARD

When Tandy first came out with the CoCo there were
several deficiencies that needed improvement. Some of them
have been taken care of and some remain to be fixed. Here is
the list to date:

1. Not enough memory. Stage I

2. Poor keyboard.

3. Poor asthetics. (Gray case)

4. Insufficient display (16 x 32)

5. Not enough online disk storage.
6.. Not enough memory. Stage 2

The display has always been a problem. You simply can-
not do much with only 16 x 32. Software packages like
O-Pak for OS-9 and several big screen packages enhance the
display, but at the cost of memory. What is really needed is a
built in display that handles at least 24 x 80.

The RS disk system is only single-sided. This limitation
becomes evident with the use of OS-9. The system disk as
purchased from Tandy has only 1 12 sectors free from the
630 that are available on the disk. Although you can up the
tracks to 40 if your drives can handle it, a double sided
capability is needed, like FLEX and even better, a hard disk
system.

When Tandy came out with thc64K CoCo, they took care
of the first memory problem. However, OS-9 uses so much
memory (capable of using up to one megabyte) that Tandy
now needs to add even more memory to make the system
truly useful.

Do not dispair. Tandy does listen to its customers; the fact
that they have upgraded the system so far is indicative of
that. So be patient, I am sure that things will improve.

MORE ROOM

Because the RS OS-9 disk has so much stuff on it there is
little left for your own files. Well, there is a way to free up a
considerable amount of room. First, you have to determine
what your needs are. You probably don't use timesharing so
you can remove the files from the /cmds directory that are
needed for that. They are tsmon and login. Other commands
that are not used often are binex, cobbler, dcheck, exbin,
sleep, and tee. Of course you may have different choices, but
you get the idea. For doing assembly work you should make
up a separate disk with the appropriate commands and
remove them from the system disk. On the disk that is not
used for assembly work you do not need the / DEFS direc-
tory. If you do not log on your system, and there is no reason
to. you do not need the /SYS directory. Basically, you have
to make up several "system" disks for each specific task you
want to perform.

On the memory side of things, you can free up a few pages
by OS9gen'ing a new boot and leave off the modules pipe-
man, piper and pipe. Ifyoudonot timeshare, then you don't
need the modules 77 and RS232. Finally, you only need the
descriptors for the drives that you have: ie. tlO and dl ' . This
will only save a few pages, but you may need the memory.
After all. once you've done it you do not need to do it again.

In order to make this column useful to you, I need input
from you, in the form of questions and suggestions, as to
what 1 should cover here. Please send them in care of the
magazine.

Coming next month ... I don't know! So, send in your
questions, or vou'll be in for as big a surprise as me.

Till then . . .
